Counts are distinct nonstop routes observed in FlightQ's tracked airline schedule data across 1,860 airports with scheduled service (snapshot 2026-07-01). A route flown by several airlines counts once; codeshares are not double-counted. Coverage reflects scheduled passenger service and is refreshed with each data update, so counts can differ from airport press releases that include seasonal or announced-but-unflown routes.
