Sec. 19–7 Passenger origin-destination

survey.

(a) All U.S. large certificated air carriers

conducting scheduled passenger

operations (except helicopter carriers)

shall participate in a Passenger Origin-

Destination (O & D) Survey covering

domestic and international operations,

as described in the instructions manual

entitled, Instructions to Air Carriers for

Collecting and Reporting Passenger Origin-

Destination Survey Statistics (Appendix

A to this section), and in Passenger

Origin-Destination Directives issued by

the Department’s Bureau of Transportation

Statistics (BTS), Office of Airline

Information (OAI). Copies of these

Instructions and Directives are provided

to each large carrier participating in

the Survey. Copies are also available

from the Office of Airline Information,

K–25, Room 4125, U.S. Department of

Transportation, 400 Seventh St., SW.,

Washington, DC 20590.

(b) Those participating air carriers

that have access to automatic data

processing (ADP) services shall utilize

magnetic tape, cartridge, floppy diskette

or other ADP media for transmitting

the prescribed data. Those carriers

without ADP capability should contact

the Office of Airline Information for

further instructions ((202) 366–4373).

(c) A statistically valid sample of

light coupons shall be selected for reporting

purposes. The sample shall consist

of at least 1 percent of the total

lifted ticket flight coupons for all large

domestic markets listed in the Instructions

and 10 percent for all others—including

domestic and international

markets. The sample shall be selected

and reported in accordance with the requirements

of paragraph (a) of their

section, except that the participating O

& D carriers with nonstandard

ticketing procedures, or other special

operating characteristics, may propose

alternative procedures. Such departures

from standard O & D Survey

practices shall not be authorized unless

approved in writing by the Director,

Office of Airline Information under the

procedures in Sec. 1–2 of 14 CFR part

241. The data to be recorded and reported

from selected lifted ticket flight

coupons, as stipulated in the Instructions

and Directives shall include the

following data elements: Point of origin,

carrier on each flight-coupon

stage, fare-basis code for each flightcoupon

stage, points of stopover or

connection (interline and intraline),

point of destination, number of passengers,

and total dollar value of ticket

(fare plus tax).

Sec. 19–7 14 CFR Ch. II (1–1–04 Edition)

(d) Data covering the operations of

foreign air carriers that are similar to

the information collected in the Passenger

Origin-Destination Survey are

generally not available to the Department,

the U.S. carriers, or U.S. interests.

Therefore, because of the damaging

competitive impact on U.S. carriers

and the adverse effect upon the

public interest that would result from

unilateral disclosure of the U.S. survey

data, the Department has determined

its policy to be that the international

data in the Passenger Origin-Destination

Survey shall be disclosed only as

follows:

(1) To an air carrier directly participating

in and contributing input data

to the Survey or to a legal or consulting

firm designated by an air carrier

to use on its behalf O & D data in

connection with a specific assignment

by such carrier.

(2) To parties to any proceeding before

the Department to the extent that

such data are relevant and material to

the issues in the proceeding upon a determination

to this effect by the Administrative

Law Judge or by the Department’s

decision-maker. Any data

to which access is granted pursuant to

this section may be introduced into

evidence subject to the normal rules of

admissability of evidence.

(3) To agencies and other components

of the U.S. Government.

(4) To other persons upon a showing

that the release of the data will serve

specifically identified needs of U.S.

users which are consistent with U.S.

interests.

(5) To foreign governments and foreign

users as provided in formal reciprocal

arrangements between the foreign

and U.S. governments for the exchange

of comparable O & D data.

(e) The Department reserves the

right to make such other disclosures of

the O & D data as is consistent with its

regulatory functions and responsibilities.

Office of the Secretary, DOT Sec. 19–7

1 Each ticket booklet is comprised of one or

more flight coupons for passenger travel in a

city-pair market, plus a passenger coupon

(the traveler’s receipt) and the auditor coupon

(for the carrier’s internal controls).

B. Narrative Description

A single O&D Survey is conducted continuously

by the large U.S. certificated air carriers.

Foreign air carriers do not directly

participate in the Survey, although some of

their data are captured in the Survey, since

passengers who share a ticketed itinerary between

a U.S. carrier and a foreign carrier

may be sampled by the U.S. carrier. The authority

for these instructions is found in 14

CFR part 241, section 19–7, and in the CAB

Sunset Act of 1984 (Pub. L. 94–443).

The Survey samples revenue passenger

trips moving in whole or in part on domestic

and/or international scheduled services of

the carriers participating in the Survey. In

general, these requirements do not apply to

small certificated, all-cargo and all charter

carriers.

The source documents for the Survey data

are passenger tickets. These data are collected

from the ‘‘lifted’’ flight coupons of

tickets (a portion of a multi-part ticket

booklet of three 1 or more coupons, including

one for each stage of the passenger’s trip

itinerary which is lifted by the carrier as the

passenger boards a particular flight segment).

The Survey data are taken from the coupon

that is lifted by a participating carrier,

unless it is apparent from the lifted coupon

that another participating carrier has already

recorded and reported the data, in

which instance the ticket coupon is non-reportable

for the second honoring/participating

carrier. The complete passenger

itinerary, and related data on type of fare

and dollar value of the ticket, is recorded as

VerDate jul<14>2003 04:17 Feb 03, 2004 Jkt 203045 PO 00000 Frm 00165 Fmt 8010 Sfmt 8010 Y:\SGML\203045T.XXX 203045T

Sec. 19–7 14 CFR Ch. II (1–1–04 Edition)

2 These summarization procedures include

showing two or more passengers with the

same itinerary as one O&D record and compressing

extremely lengthy itineraries (such

as around-the-world tickets) into a standard

trip stage length limit (which may be either

seven or twenty-three stages, at the carrier’s

option), as explained in Section V.D.

3 Magnetic tapes, floppy discs and similar

media will be returned to the carriers, upon

request, following completion of the processing

cycle by the Department.

one entry from the sampled, reportable

flight coupon.

The recording of data from the sampled

flight coupon normally consists of transcribing

the information exactly as indicated

on the ticket. The detail recorded for each

trip shows the complete routing from the origin

city (airport code) to the destination

city (airport code) including, in sequence

from the origin, each point of transfer and

stopover (intraline and interline), the summarized

fare-basis code shown for each flight

coupon stage of the itinerary, and the total

dollar value of the fare and tax for the entire

ticket.

Prior to 1987, the Survey was generally

based on a 10-percent sample of passenger

tickets. Beginning July 1, 1987, the Survey is

collected primarily on the basis of a stratified,

scientific sample of at least 1 percent of

tickets in domestic major markets and 10

percent of tickets in all other domestic and

in all international city-pair markets. The

Survey data are taken from the selected

flight coupons of the tickets sampled: singlecoupon

or double-coupon round trips in domestic

major markets where the ticket serial

number ends in double zero (00) and all

other ticket coupons ending in zero (0). This

procedure yields a ‘‘two-tiered’’ stratified

sample.

Group tickets are included on the basis of

a 10-percent sample when the number of passengers

on such a group ticket is 10 or less.

Group tickets with more than 10 passengers

on each ticket are included on the basis of a

100 percent census, i.e., all such tickets are

sampled, regardless of serial number, and the

total data listed are conformed to a 10 percent

sample for inclusion in the O&D Survey.

Following the selection of reportable flight

coupons and the recording of data, each participating

carrier shall edit and summarize 2

the data into a quarterly report to the Department.

II. EFFECTIVE DATE OF INSTRUCTIONS

These data collection and reporting instructions

are effective on and after July 1,

1987 and apply to all flight coupons lifted on

or after July 1, 1987.

III. CARRIERS PARTICIPATING IN SURVEY

A. Participating carriers. As defined in section

19–7 of the Department’s Economic Regulations

(14 CFR part 241), the participants

in the O&D Survey include all large certificated

air carriers conducting scheduled passenger

services (except helicopter carriers).

These participating carriers collect and report

data in accordance with these Instructions,

and supplemental Passenger Origin-Destination

Directives that may be issued periodically.

The list of participating carriers will

be issued by reporting directive under the

authority in 14 CFR 385.27(b).

B. Amendments to list of participating carriers.

As new carriers begin service, they will

be required to file O&D Survey Data. These

carriers will not be added to the participating

carrier list automatically, but will be

added when the next annual review is made.

IV. SUBMISSION OF REPORTS

A. Period covered by reports. Reports are to

be filed for each calendar quarter of the year

as shown below:

Report Time period covered

1st quarter ............................... Jan. 1 through Mar. 31.

2nd quarter ............................. Apr. 1 through June 30.

3rd quarter .............................. July 1 through Sept. 30.

4th quarter .............................. Oct. 1 through Dec. 31.

B. Filing date for reports. Reports are to be

filed with the Department on or before the

dates listed below. The mailing address is on

the inside cover to these instructions.

Report Due date 1

1st quarter ............................................... May 15

1 Due dates falling on Saturday, Sunday or national holiday

will become effective the first following work day.

C. Format of report. The report may be submitted

in any one of the following formats:

(1) ADP media including magnetic tapes

and floppy discs.3

(2) Hard copy BTS Form 2787, in typewritten

form, for carriers that lack computer

capability. Sample formats of the required

data appear in Sections IX and XII.

Supplies of blank Form 2787 are available,

upon request, from the Director, Office of

Airline Information (address on inside

cover). Any reasonable facsimile of Form

2787 will be acceptable in lieu of Form 2787,

if approved in advance by the Director.

D. Number of copies of report to be filed. A

participating carrier shall file with the Department

a single copy of its quarterly O&D

data report. When ADP submissions are

transmitted, the package is to contain a

transmittal letter describing the contents,

and stating the overall record and passenger

Office of the Secretary, DOT Sec. 19–7

4 Upon approval of the Director, Office of

Airline Information, carriers may continue

current reporting procedures (up to twentythree

stages of a passenger flight) and may

report a uniform 10 percent sample of tickets

lifted (each zero ending lifted coupon) without

reducing the sample size from 10 percent

to 1 percent for domestic major markets.

Note that the domestic major markets will

be reviewed each year at June 30, based on

the prior 12 months O&D data, and the list

amended as necessary. The list could remain

static for more than a year, although it will

be reviewed annually. Necessary amendments

will be effective on January 1 of the

following year.

5 Codes to be used are those appearing in

the Official Airline Guide at the time the data

are being recorded. If a code is not found in

the OAG, contact the Director, Office of Airline

Information (address inside front cover).

counts included in the submission. Each submission

is to be labeled externally as to submitting

carrier and time period of the O&D

Survey data.

E. Address for filing reports. Reports should

be submitted to the Director, Office of Airline

Information (address on inside cover).

V. SELECTION OF SAMPLE AND RECORDING OF

DATA.4

A. Sampling Basis. Each participating carrier

in this O&D Survey shall search all listed

flight coupons, whether the coupons are

its own ticket stock or on the ticket stock of

another U.S. or foreign carrier (either standard

IATA and ARC ticket stock or nonstandard

ticket stock), and is to select for reporting

purposes the following flight coupons:

(1) Major domestic markets. All single-passenger

flight coupons that are either a single

flight coupon ticket or part of a round trip,

two coupon ticket where the ticket serial

number ends in the digits double-zero (00).

NOTE.—The list of major domestic markets

will be issued by reporting directive under

the authority in 14 CFR 385.27(b).

(2) International markets and all other domestic

markets. (a) All single-passenger flight

coupons with ticket serial numbers ending

with the digit zero (0);

(b) Those group-ticket flight coupons with

10 or fewer passengers with ticket serial

numbers ending with the digit zero (0);

(c) Those group-ticket flight coupons with

11 or more passengers without regard to serial

number; and

(d) Itineraries in major domestic markets

that comprise more than two coupons are

sampled on a uniform 10 percent basis, by selecting

all ticket serial numbers ending with

the digit zero (0).

B. Selection of Reportable Flight Coupons.

The flight coupons identified above are to be

examined to isolate the reportable flight

coupons, i.e. coupons from which data are to

be recorded. Flight coupon data are reported

only by the first honoring and participating

carrier (operating carrier). Such carriers

shall report the required data for the entire

ticketed itinerary.

If a participating carrier has preceded an

examining carrier on any stage in the trip

itinerary, including any stage in a conjunction

itinerary and any stage in a reissued

ticket (either before or after reissue) that

coupon is not reportable.

For conjunction tickets, the ticket number

for the first ticket booklet determines if the

conjunction tickets should be reported in the

Survey. Otherwise, conjunction tickets do

not require special treatment and are governed

by the rules for regular tickets.

No adjustment is made in the Survey for

alterations or changes in the trip itinerary

subsequent to the stage covered by the reportable

coupon.

C. Optional Use of Other Sampling Procedures.

(1) Alternative sampling procedures or alternative

O&D data systems may be proposed

by participating carriers with nonstandard

ticketing procedures, or other special

operating characteristics. Data reported

under proposed alternative procedures must

approximate the usefulness and statistical

validity of the O&D Survey.

(2) Such departures from the prescribed

O&D Survey practices shall not be authorized

unless approved in writing by the Director,

Office of Airline Information (address inside

front cover). The proposed alternative

O&D Survey procedures must be described in

detail in the letter requesting the waiver.

D. Recording of Data from Reportable Flight

Coupons. (1) The following items are to be reported

from the reportable flight coupons:

(a) Point of origin,

(b) Operating carrier on each flight stage

(if unknown, identify ticketed carrier),

(c) Ticketed carrier on each flight stage,

(d) Fare-basis on each flight coupon, C, D,

F, G, X or Y,

(e) Points of stopover or connection (interline

and intraline),

(f) Point of destination,

(g) Number of passengers, and

(h) Total dollar value of ticket (fare plus

tax and other charges, such as Passenger Facility

Charges).

(2) The individual items are to be recorded

in the sequence of occurrence in the

itinerary as follows:

(a) All entries for points (airport codes 5) in

an itinerary are to be recorded in three-letter

airport code data to fit into the stagelength

limitation (seven or twenty-three

stages at the carrier’s option), all airport

codes are to be reported, including data on

VerDate jul<14>2003 04:17 Feb 03, 2004 Jkt 203045 PO 00000 Frm 00167 Fmt 8010 Sfmt 8010 Y:\SGML\203045T.XXX 203045T

168

Sec. 19–7 14 CFR Ch. II (1–1–04 Edition)

commuter, foreign, intra-state and other

carriers’ portions of itineraries. Normally

codes are recorded as they appear on the

ticket. However, if a code is obviously incorrect,

record the correct code. For instance, if a

ticket is coded DCA–NYC or Washington/National

to New York when the flight stage actually

operated from Washington, Dulles to

Newark (EWR), record the correct airport

code. When only name spellings of a city appear

on the ticket for multi-airport cities

(such as Washington, New York, San Francisco,

or Los Angeles), record the specific

three letter airport code. In cases where two

airport codes are shown on the ticket for a

point, such as when the passenger arrives at

an airport such as San Francisco and departs

from another local airport such as Oakland,

record the code for the arrival airport, enter

a surface segment indicator (—) to the departure

airport, and record the departure airport

code. (When the surface portion is at

the beginning or end of an itinerary, the surface

indicator is to be omitted). For example:

In the above example, the passenger trip

stages or segments are compressed into the

maximum of 7 stages so that several intermediate

city-pairs (Los Angeles to Seattle to

Anchorage, or LAX—SEA—Anc) and the related

carriers have not been recorded, as prescribed

below in this Section V.D.(3)(e). In

addition, after the fourth city-pair (Los Angeles-

Salt Lake City), the passenger trip

itinerary moves from the initial four-part

ticket booklet onto another ‘‘conjunction’’

ticket, and the summary fare code data are

not recorded beyond the initial four-part

ticket.

(b) All entries for operating and ticketed

carriers for a coupon stage of an itinerary

are to be recorded using two character IATAassigned

or DOT codes, as in the above example.

Note that the fare code summary was

properly inserted after the ticketed carrier’s

code, i.e., UA for United Air Lines and Y for

unrestricted coach class service. When a twocharacter

carrier code is shown on the ticket,

record that code for the ticketed carrier.

However, if a code is obviously incorrect,

record the correct carrier code. If the reporting

carrier does not know the operating carrier

on a downline code-share segment, it

would use the ticketed carrier’s code for

both the operating and ticketed carriers. The

reporting carrier is not responsible for knowing

the operating carrier of a downline codeshare

where it is not a party to the codeshare

segment. Except for the infrequent

compression of data to fit into the stagelength

limitation (7 or 23 stages at the carrier’s

option), all carrier codes are to be recorded,

including data on air taxis, commuters,

intra-state, and other carrier portions

of itineraries. On tickets involving

interchange service or other cooperative carrier

arrangements, the juncture point(s)

where the passenger moves from one carrier

VerDate jul<14>2003 04:17 Feb 03, 2004 Jkt 203045 PO 00000 Frm 00168 Fmt 8010 Sfmt 8010 Y:\SGML\203045T.XXX 203045T

169

Office of the Secretary, DOT Sec. 19–7

system to another is to be recorded as an intermediate

point in the itinerary, even when

not shown on the ticket and even though the

flight may overfly the juncture point.

(c) Entries for fare-basis codes are to be

taken from the ‘‘fare basis’’ and ‘‘fare description’’

portions of the ticket and simplified

into the appropriate category, as

shown below. No attempt shall be made to

determine and record fare-basis codes for

that portion of a conjunction ticket appearing

in the ticket. Fare-basis codes are to be

recorded in one-character alphabetic codes.

The fare-basis codes are recorded as follows:

C—Unrestricted Business Class

D—Restricted Business Class

F—Unrestricted First Class

G—Restricted First Class

X—Restricted Coach/Economy Class

Y—Unrestricted Coach/Economy Class

U—Unknown (This fare category is used

when none is shown on a ticket coupon, or

when a fare category is not discernible, or

when two or more carrier fare codes are

compressed into a single stage of a passenger

trip).

(d) In recording the number of passengers,

each single-passenger ticket is to be recorded

as one passenger. Tickets for infants

under two years of age not occupying a seat

are not to be counted. A revenue passenger is

defined in Section X.

For group tickets of 10 or fewer passengers

per ticket record the actual number of passengers

on each ticket, i.e., either 2, 3, 4, 5, 6,

7, 8, 9 or 10. For group tickets with 11 or

more passengers (those sampled at a 100-percent

rate) record the actual number of passengers

traveling on each ticket, but keep

these entries separate from the group ticket

records with 10 or fewer passengers and from

the single-passenger ticket records. Group

tickets with 11 or more passengers are to be

sorted and summarized to combine all passengers

for all itineraries which are identical

in every respect, i.e., points, carriers, fare

basis codes, and average dollar value (as defined

in paragraph (e), below). The total

number of passengers on each summarized

record is to be divided by 10, rounding to the

nearest whole passenger. If the quotient ends

in 0.5 or more, raise to the next whole passenger.

If the quotient ends in less than 0.5,

drop the fraction. These large group-ticket

records, after division by 10 for compatibility

with the other data, are to be merged

with the single-passenger records and with

the group-ticket entries from tickets of 10 or

fewer passengers for the quarterly O&D Survey

report.

(e) The total dollar value shall be taken

from the ‘‘Total’’ box on each ticket and

shall be the sum of the fare plus tax for the

entire ticket. Record this amount in whole

U.S. dollars, with the cents dropped. Do not

round cents to nearest whole dollar.

Amounts on tickets stated in foreign currency

are to be converted to U.S. dollar

equivalents. For all group tickets, the dollar

value to be recorded shall be the average

amount per passenger, determined by dividing

the total dollar value for the entire

group by the number of passengers on the

group ticket, dropping cents in the average

amount.

(3) The length of the itineraries to be recorded

is limited to a maximum of seven stages or

twenty-three stages, at the carrier’s option.

This recognizes that the vast majority of

tickets sampled have seven stages or fewer

and that the rare occurrences of extremely

lengthy itineraries do not impact the overall

Survey results enough to justify their reporting

burden. Therefore, trips longer than

these limits are compressed to fall within the

stated maximums. The ticketed origin and

destination are retained, but the intermediate

routing is compressed by applying the following

rules, in sequence:

(a) Combine any contiguous open, unknown

carrier, or surface stages eliminating

the connecting point, and ignoring the farebasis

codes, if different:

(b) Combine any contiguous stages via the

same non-U.S. carrier, eliminating the connecting

point, and ignoring the fare-basis

codes, if different;

(c) Combine any contiguous stages via different

non-U.S. carrier, making the carrier

‘‘UK’’, eliminating the connecting point, and

ignoring fare-basis codes, if different:

(d) Combine any contiguous stages via the

same U.S. carrier, eliminating the connecting

point, and ignoring the fare-basis codes, if

different, and;

(e) If the trip, after applying the four steps

above, is still too long, record the compressed

routing through to the stage length

limitation city (seventh or twenty-third

city), enter UK as the final carrier, and then

record the ticketed destination as the next

(the 8th or 24th) city.

VI. SUMMARIZATION OF RECORDED DATA

A. General. Prior to the submission of each

quarterly report to the Department, each

carrier is to summarize the data in accordance

with the rules in Section VI.B. In special

hardship cases, carriers may submit a

waiver request (with justification under Section

1–2 of 14 CFR part 241) requesting permission

to report their flight coupon records

exactly as represented on their lifted tickets.

Waiver requests must provide the documentation

described in Section VI.C. so that

the Department can develop the necessary

procedures and edit routines to ensure the

accuracy and reliability of the overall O&D

Survey results. The granting of such waivers

will depend upon the availability of resources

for the Department to assume this

VerDate jul<14>2003 04:17 Feb 03, 2004 Jkt 203045 PO 00000 Frm 00169 Fmt 8010 Sfmt 8010 Y:\SGML\203045T.XXX 203045T

170

Sec. 19–7 14 CFR Ch. II (1–1–04 Edition)

additional burden, which can only be determined

on a case by case basis, after evaluating

each carrier’s need.

B. Rules for Summarization. Sort the recorded

entries into sequence by the entire

record (excluding the passenger field), i.e., by

origin, complete routing (including farebasis

codes), tickets destination, and dollars

value of ticket. All identical records are then

to be combined into one summary record. The

number of passengers on the summary record

is to be the sum of the passenger amounts of

all the individual records combined. Passengers

are only summarized where records

are identical in all respects except in number

of passengers including dollar value of ticket.

NOTE: DO NOT SUMMARIZE DOLLARS

OVER IDENTICAL RECORDS. This summarization

is to include the entries from group

tickets, but only after the entries for group

tickets with 11 or more passengers have been

summarized and divided by 10, as stated in

Section V.D.(2)(d). Carriers submitting quarterly

O&D Survey reports on magnetic tapes

or similar formats such as ‘‘floppy discs’’

will follow the ADP INSTRUCTIONS in Section

IX. Carriers filing reports on hardcopy

BTS Forms 2787 are to enter, on the last page

of the report, the overall total of the number

of passengers in the report.

C. Waiver Requests. Requests for permission

to depart from the required O&D Survey procedures

should include a procedural statement

describing the process the carrier proposed

to employ in examining, selecting and editing

the data from reportable flight coupons for

the O&D Survey, as well as a flow chart diagramming

the proposed procedures.

D. Quantity and Quality Controls. Carriers

are expected to establish and maintain continuous

quantity and quality controls on the

flow of all lifted flight coupons through their

system processes to determine the total

number of coupons handled and the number of

reportable coupons selected. Such data controls

and tests have not been specified by the

Department, and necessarily must be developed

by each carrier. Each participating carrier

shall develop and use on a continuous

basis such control tests as are necessary to

ensure that all reportable coupons are being

selected, recorded and reported as intended

by these O&D Survey Instructions. Such controls

should extend over all ADP processing,

both in-house and that from external service

bureaus.

VII. EDITING OF RECORDED DATA

A. City and Airport Codes. Prior to submission

of O&D Survey reports, each carrier is

to edit the recorded data to validate city and

airport codes. This edit is to verify that the

codes recorded are valid official codes, and it

is independent of whether or not the carriers

shown actually operated into or out of the

airport shown. Any questions about airport

codes should be addressed to the Director,

Office of Airline Information (see inside of

cover).

B. Edit Responsibility of Carriers. Each carrier

is responsible for developing edit procedures

and internal controls over its data

entry and processing procedures so that

valid and reliable data are captured in the

O&D Survey inputs and are properly summarized

in the outputs. Since the carriers have

many different statistical systems, it is not

practicable for the Department of Transportation

to prescribe specific controls in this

area, and each carrier is responsible for developing

the appropriate internal control

procedures to edit the O&D Survey data and

ensure the integrity of these data. The Department

will control the accuracy of its

processing of the sampled data upon receipt

from the carriers.

C. System Documentation of Edits. Carriers

are required to maintain written O&D Survey

procedural statements and flow charts.

As provided in Section VIII, these must be

established, or re-certified as of July 1, 1987,

and thereafter when significant procedural

revisions occur.

VIII. CONTROL OF SAMPLE SELECTION AND

DATA RECORDING

A. Sample Accuracy and Reliability. In order

to maximize the accuracy and reliability of

the sample selection and data recording,

each carrier is to:

(1) Develop a written statement describing

the procedures it will employ in examining

and selecting reportable flight coupons and

in recording, summarizing, editing, and testing

the Survey data.

(2) Submit any proposed changes in the

above procedures to the Department’s Office

of Airline Information, prior to implementation

of such changes.

(3) Establish continuous quantity controls

on the flow of all lifted flight coupons

through the carrier’s accounting processing

to determine the total number of coupons

handled, and the number of reportable coupons

selected. Tests are to be made continuously

to assure that all reportable coupons

are being selected and the data recorded.

Such tests should be completed while the

‘‘lifted’’ flight coupons (representing earned

passenger revenues for flight segments operated)

remain in the possession of the carrier.

Establish such other internal control procedures

as are necessary for supervising and

monitoring the accuracy of the recording of

data from reportable flight coupons.

B. Staff Review. The OAI staff will review

the carrier procedures and practices and may

request modifications or the use of special

procedures necessary to improve the sample

or to bolster the controls for accuracy and

reliability.

(2) Detail record. (a) All records are to be

summarized on the complete itinerary 7 (columns

7 through 200) and the summary record

only for each itinerary is to be submitted.

The tape file, including the identification

record, is to be in sequence by complete

itinerary.

(b) The tape record layout is shown on the

following page.

(3) Magnetic Tape Instructions: (a) All

tapes are to be written using the standard

IBM extended binary coded decimal interchange

code (EBCDIC).

(b) The recording density can be either 6250

or 1600 B.P.I.

(c) All tape will contain standard IBM volume

header, and trailer records.

(d) External labels will contain the carrier,

name, the report date, file identification,

and an address for returning the tapes.

(4) Transmittal letter. The tape shall be accompanied

by a transmittal letter which

shows the number of records reported and

the total number of passengers contained in

the report.

B. Editing of Tape Records. Prior to submission

of data, each carrier is requested to edit

and correct its data so that its O&D Survey

report may be as error-free as is reasonably

practicable. The methods to be used in editing

are left to the carriers’ discretion, but

with assistance available upon request from

the Department’s Office of Airline Information

(OAI). To aid the carriers in maintaining

a current file of editing criteria, OAI will

re-issue, as needed, the city/airport-carrier

file to each participating carrier. There will

be a five-position field to denote the city/airport-

carrier. The first three positions denotes

the airport and the last two positions

denotes the air carrier.

C. Standard Formats for Floppy Disk or

Cartridge Submissions. Carriers should use

the 200 position format with the standard

length fields prescribed for magnetic media

submissions. The record layout is detailed in

subsection A(1) of this section. However, to

simplify the PC submissions, the submitter

may report the dollar value of the ticket in

the field immediately after the last reported

city code, rather than in positions 196–200.

Submitters may separate fields by using

commas or tabs (comma delimited ASCII or

tab delimited ASCII format).
