Source: FlyerIntel analysis of US DOT BTS data · July 2023 – August 2026 · A flight number is a slot in a schedule and gets reassigned to different city pairs over time, so each is measured only on the route it currently operates. Numbers with fewer than 600 operations on that route, or last flown more than a quarter ago, are not listed. Schedules change — confirm a departure still operates before booking around it.
