What shapes Allegiant Air's record
Allegiant's record changes sharply by airport. Its flights from AZA ran 16.2% late, against 30.3% from Fort Lauderdale (FLL) (airports with at least 5,000 Allegiant departures).
Delays peak in July (31.2%) and are lowest in September (18.7%).
BTS reports each flight under the carrier that operated it. Flights flown by regional partners such as SkyWest, Republic, Envoy, PSA and Endeavor are reported under those operators, so this is the record of Allegiant's own aircraft and crews.
