Straight answers about U.S. Bureau of Transportation Statistics – TranStats data
What is the T-100 data bank?
The Air Carrier Statistics database: monthly domestic and international market and segment traffic that certificated US carriers report on Form T-100. Seven published tables cover Domestic and International, Market and Segment, in all-carriers and US-only variants, plus combined Market and Segment tables, running from 1990 to 2026.
How large is the T-100 segment table?
The combined Segment table holds 14,083,343 records across 50 documented fields, observed monthly with data through May 2026. Single years of segment detail run to millions of records, which is why Datadory delivers it typed, keyed and cut to scope rather than as raw dumps.
Which carriers report into Form 41 Traffic?
Certificated US air carriers - those holding Certificates of Public Convenience and Necessity with annual operating revenues of $20 million or more - report monthly under 14 CFR 241. That mandate is why the series reaches virtually the entire US scheduled fleet, passenger and all-cargo alike.
How are airlines tracked consistently across years?
Through the four unique-carrier identifiers plus AirlineID, the stable US DOT number that survives code changes, renames and mergers. A documented carrier-merger note explains the mapping, and Datadory resolves it once so your panels never double-count a merged airline.
