Intra-Alaska Air Carrier Statistics

Per Alaska Accounting and Reporting Directive, Alaska bush carriers report their traffic data to the Bureau of Transportation (BTS) Office of Airline Information (OAI) via the T-100 Reporting System, which is comprised of two types of records: (1) Nonstop Segment Records and (2) On-Flight Market Records.

BTS processes the data for the U.S. Postal Service (USPS) which uses the market (MKT) and segment (SEG) files to determine the “qualified” air carriers for the tender of non-priority bypass mail in the Intra-Alaska Bypass Mail System.

The data are released per a regular schedule. On or about the second Thursday of each month, BTS posts three sets of Intra-Alaska Air Carrier Statistics – a "FINAL" Month's release, that is in sync with other T100 data products being released, an "initial release" of the coming Month's data, and a "preliminary release" of the most recent data reported.

Carriers currently using inter-village market conversions are listed in Table 1.

Note: Beginning August 1, 2005, before sending the T100 data to the U.S. Postal Service, OAI combines data, for the 12 months ending, from Frontier Flying Service (2F) and Cape Smythe Air Service (6C).
