US domestic passenger & freight traffic by route

Coverage. 4,879 of 5,349 domestic-eligible route pages (91.2%) matched a real 2025 BTS T-100 Domestic Segment record for scheduled passenger service (BTS class F) and now carry a "BTS domestic traffic" section with 2025 passengers, freight, mail, departures scheduled/performed, a per-carrier breakdown, and aircraft types flown. The remaining 470 domestic-eligible pages are untouched: BTS has no matching scheduled-passenger record for that exact directed city pair in 2025 (commonly a small general-aviation field, a seaplane/on-demand-only operation, or a route in the OpenFlights snapshot that has since been discontinued — OpenFlights' own data is frozen as of 2014). International route pages (30,241 of them) are also untouched: BTS T-100 Domestic Segment data only covers segments where both endpoints are in the United States or a US territory, by design, so no volume claim is made for international city pairs.

Total freight carried across all enriched routes in 2025: 1,086,763,094 lb. Total mail: 127,482,248 lb.

Methodology summary

Source: BTS T-100 Domestic Segment (All Carriers), U.S. DOT Bureau of Transportation Statistics — a public-domain U.S. government work. Full calendar year 2025 (the most recent complete year available; 2026 monthly data was not yet published in the source's own year selector at fetch time, 2026-07-25). Scheduled passenger service (BTS class F) only; all-cargo and non-scheduled service are excluded from these figures. Matching is exact: a route page's (origin, destination) IATA pair must equal a BTS-reported (origin, destination) pair — no fuzzy matching, no merging of nearby airports, no gap-filling for unmatched routes.
