Interstate air transportation means the transportation of passengers or property by aircraft as a common carrier for compensation, or the transportation of mail by aircraft—

(1) Between a place in—

(i) A State, territory, or possession of the United States and a place in the District of Columbia or another State, territory, or possession of the United States;

(ii) Hawaii and another place in Hawaii through the airspace over a place outside Hawaii;

(iii) The District of Columbia and another place in the District of Columbia; or

(iv) A territory or possession of the United States and another place in the same territory or possession; and

(2) When any part of the transportation is by aircraft.

Reporting carrier for Schedule T-100 purposes means the air carrier in operational control of the aircraft, i.e., the carrier that uses its flight crew under its own FAA operating authority.

Section 41102 carrier means an air carrier certificated under section 41102 of the Statute to transport persons, property and mail or property and mail only.

Section 41103 carrier means an air carrier holding a certificate issued under section 41103 of the Statute to provide all-cargo air transportation.

Service, scheduled cargo means transport service operated pursuant to published flight schedules including extra sections. There is no requirement on the number of weekly flights nor is there a requirement that the schedule be published in the Official Airline Guide.

Wet-Lease Agreement means an agreement under which one carrier leases an aircraft with flight crew to another air carrier.

§291.44   BTS Schedule P-12(a), Fuel Consumption by Type of Service and Entity.

(a) For the purposes of BTS schedule P-12(a), type of service shall be either scheduled service or nonscheduled service as those terms are defined in §291.45(c)(2) and (3).

(b) For the purpose of this schedule, scheduled service shall be reported separately for:

(1) Intra-Alaskan operations;

(2) Domestic operations, which shall include all operations within and between the 50 States of the United States (except Intra-Alaska), the District of Columbia, the Commonwealth of Puerto Rico and the United States Virgin Islands, or a U.S. territory or possession to a place in any State of the United States the District of Columbia, the Commonwealth of Puerto Rico and the United States Virgin Islands, or a U.S. territory or possession;

(3) International operations are flight stages with one or both terminals outside the 50 States of the United States, the District of Columbia, the Commonwealth of Puerto Rico and the United States Virgin Islands, or a U.S. territory or possession.

(c) For the purpose of this schedule, nonscheduled service shall be reported separately for domestic operations and international operations as defined in paragraphs (b)(2) and (b)(3) of this section, except that domestic and international Military Airlift Command (MAC) operations shall be reported on separate lines.

(d) The cost data reported on each line shall represent the average cost of fuel, as determined at the station level, consumed in that geographic entity.

(e)(1) The cost of fuel shall include shrinkage, but excludes:

(i) “Throughput” and “in to plane” fees, i.e., service charges or gallonage levies assessed by or against the fuel vendor or concessionaire and passed on to the carrier in a separately identifiable form; and

(ii) Nonrefundable Federal and State excise taxes.

(2) However, “through-put” and “in to plane” charges that cannot be identified or segregated from the cost of fuel shall remain a part of the cost of fuel as reported on this schedule.

(f) Each air carrier shall maintain records for each station showing the computation of fuel inventories and consumption for each fuel type. The periodic average cost method shall be used in computing fuel inventories and consumption. Under this method, an average unit cost for each fuel type shall be computed by dividing the total cost of fuel available (Beginning Inventory plus Purchases) by the total gallons available. The resulting unit cost shall then be used to determine the ending inventory and the total consumption costs to be reported on this schedule.

(g) Where amounts reported for a specific entity include other than Jet A fuel, a footnote shall be added indicating the number of gallons and applicable costs of such other fuel included in amounts reported for that entity.

(h) Where any adjustment(s) recorded on the books of the carrier results in a material distortion of the current month's schedule, carriers shall file a revised Schedule P-12(a) for the month(s) affected.

[Doc. No. OST 98-4043, 67 FR 49227, July 30, 2002]

§291.45   BTS Schedule T-100, U.S. Air Carrier Traffic and Capacity Data by Nonstop Segment and On-Flight Market.

(a) Each section 41103 all-cargo air carrier shall file Schedule T-100, “U.S. Air Carrier Traffic and Capacity Data by Nonstop Segment and On-Flight Market”.

(b) Schedule T-100 shall be filed monthly.

(1) Schedule T-100 collects summarized flight stage data and on-flight market data for revenue flights. All traffic statistics shall be compiled in terms of each flight stage as actually performed. The detail T-100 data shall be maintained in such a manner as to permit monthly summarization and organization into two basic groupings. First, the nonstop segment information which is to be summarized by equipment type, within class of service, within pair-of-points, without regard to individual flight number. The second grouping requires that the enplanement/deplanement information be broken out into separate units called on-flight market records, which shall be summarized by class of service, within pair-of-points, without regard for equipment type or flight number.

(2) Joint-service operations. The Department may authorize joint-service operations between two direct air carriers. Examples of these joint-service operations are: blocked-space agreements; part-charter agreements; code-sharing agreements; wet-lease agreements, and similar arrangements.

(i) Joint-service operations are reported by the carrier in operational control of the flight, i.e., the carrier that uses its flight crews under its own FAA operating authority. The traffic moving under these agreements is reported on Schedule T-100 the same way as any other traffic on the aircraft.

(ii) If there are questions about reporting a joint-service operation, contact the BTS Assistant Director—Airline Information (fax no. 202 366-3383, telephone no. 202 366-4373). Joint-service operations are reported in Schedule T-100 in accordance with this paragraph (b).

(iii) Operational control. The air carrier in operational control of the aircraft (the carrier that uses its flight crews under its own FAA operating authority) must report joint services.

(c) Service classes. (1) The statistical classifications are designed to reflect the operating characteristics attributable to each distinctive type of service offered. The combination of scheduled and nonscheduled operations with passenger, all-cargo, and military services are placed into service classes as follows:

Code Type of service
FScheduled Passenger/Cargo.
GScheduled All-Cargo.
LNonscheduled Civilian Passenger/Cargo/
PNonscheduled Civilian Cargo.
NNonscheduled Military Passenger/Cargo.
RNonscheduled Military Cargo.

(2) Scheduled services include traffic and capacity elements applicable to air transportation provided pursuant to published schedules and extra sections of scheduled flights. Scheduled Passenger/Cargo (Service Class F) is a composite of first-class, coach, and mixed passenger/cargo service.

(3) Nonscheduled services include all traffic and capacity elements applicable to the performance of nonscheduled aircraft charters, and other air transportation services not constituting an integral part of services performed pursuant to published flight schedules.

(d) Air transport traffic and capacity elements. Within each of the service classifications, carriers shall report air transport traffic and capacity elements. The elements are reported on segment and/or market records as follows:

Appendix to §291.45—Instructions to U.S. Air Carriers for Reporting Traffic and Capacity Data on Schedule T-100

(a) Format of reports—(1) Automatic Data Processing (ADP) magnetic tape. Refer to paragraph (d) of this appendix for instructions pertaining to mainframe and minicomputer reporting. The Department will issue “Accounting and Reporting Directives” to make necessary technical changes to these T-100 instructions. Technical changes which are minor in nature do not require public notice and comment.

(2) Microcomputer diskette—(i) Optional specification. If an air carrier desires to use its personal computers (PC's), rather than mainframe or minicomputers to prepare its data submissions, the following specifications for filing data on diskette media apply.

(ii) Reporting medium. Microcomputer ADP data submission of T-100 information must be on IBM compatible disks. Carriers wishing to use a different ADP procedure must obtain written approval to do so from the BTS Assistant Director—Airline Information. Requests for approval to use alternate methods must disclose and describe the proposed data transmission methodology. Refer to paragraph (i) of this appendix for microcomputer record layouts.

(iii) Microcomputer file characteristics. The files will be created in ASCII delimited format, sometimes called Data Interchange Format (DIF). This form of recording data provides for variable length fields (data elements) which, in the case of alphabetic data, are enclosed by quotation marks (“) and separated by a comma (,) or tab. Numeric data elements that are recorded without editing symbols are also separated by a comma (,) or tab. The data are identified by their juxtaposition within a given record. Therefore, each record must contain the exact number of data elements, all of which must be juxtapositionally correct. Personal computer software including most spreadsheets, data base management programs, and BASIC are capable of producing files in this format.

(i) Record layouts for microcomputer diskettes. The record layouts for diskette are generally identical to those shown for magnetic tape, with the exception that delimiters (quotation marks, tabs and commas) are used to separate fields. It is necessary that the order of fields be maintained in all records.

(1) File characteristics. The files will be created in ASCII delimited format, sometimes called Data Interchange Format (DIF). This form of recording data provides for variable length fields (data elements) which, in the case of alphabetic data, are enclosed by quotation marks (“) and separated by a comma (,) or tab. Numeric data elements that are recorded without editing symbols are also separated by a comma (,) or tab. The data are identified by their juxtaposition within a given record. Therefore, it is critical that each record contain the exact number of data elements, all of which must be juxtapositionally correct. PC software including most spreadsheets, data base management programs, and BASIC produce minidisk files in this format.

(2) File naming conventions for diskettes. For microcomputer reports, each record type should be contained in a separate DOS file on the same physical diskette. The following DOS naming conventions should be followed:

(i) Record type S = SEGMENT.DAT

(ii) Record type M = MARKET.DAT

Subpart G—Public Disclosure of Data

§291.60   Public disclosure of data.

(a) Detailed domestic on-flight market data and nonstop segment data, except military data, shall be made publicly available after processing. Domestic data are defined as data from air transportation operations from a place in any State of the United States, the District of Columbia, the Commonwealth of Puerto Rico and the Virgin Islands, or a U.S. territory or possession to a place in any State of the United States, the District of Columbia, the Commonwealth of Puerto Rico and the Virgin Islands, or a U.S. territory or possession. Domestic military operations are reported under service codes N or R.

(b) Detailed international on-flight market and nonstop segment data in Schedule T-100 and Schedule T-100(f) reports, except military data, shall be publicly available immediately following the Department's determination that the database is complete, but no earlier than six months after the date of the data. Military operations are reported under service codes N or R. Data for on-flight markets and nonstop segments involving no U.S. points shall not be made publicly available for three years. Industry and carrier summary data may be made public before the end of six months or the end of three years, as applicable, provided there are three or more carriers in the summary data disclosed. The Department may, at any time, publish international summary statistics without carrier detail. Further, the Department may release nonstop segment and on-flight market detail data by carrier before the end of the confidentiality period as follows:

(1) To foreign governments as provided in reciprocal arrangements between the foreign country and the U.S. Government for exchange of on-flight market and/or nonstop segment data submitted by air carriers of that foreign country and U.S. carriers serving that foreign country.

(2) To parties to any proceeding before the Department under Title IV of the Federal Aviation Act of 1958, as amended, as required by an Administrative Law Judge or other decision-maker of the Department. Parties may designate agents or consultants to receive the data in their behalf, provided the agents or consultants agree to abide by the disclosure restrictions. Any data to which access is granted pursuant to this provision may be introduced into evidence, subject to the normal rules of admissibility.

(3) To agencies or other components of the U.S. Government for their internal use only.
