What shapes Frontier Airlines' record
Frontier's record changes sharply by airport. Its flights from Sky Harbor (PHX) ran 22.4% late, against 37.6% from Atlanta (ATL) (airports with at least 5,000 Frontier departures).
Delays peak in June (39.2%) and are lowest in November (22.3%).
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 Frontier's own aircraft and crews.
