F9 delay-share reading

Across 968,030 BTS-reported flights (2020–2025), Frontier Airlines posts 73.7% on-time, 5.3 points below the 79% national flight-weighted average, with 255,075 delayed arrivals and 23,192 cancellations (2.40% of the book). When a flight runs late, the average delay is 80.3 minutes.

Delay minutes concentrate in Late Aircraft (48.3% late-aircraft, 29.7% carrier, 19.5% NAS, 2.5% weather, 0.0% security across 19,546,403 total delay minutes). That mix is this carrier’s fingerprint, not a fleet-wide template sentence.

On the multi-year calendar, F9 is strongest in September (78.3% on-time on about 13,524 flights per month) and weakest in June (67.0%). The 11.3-point seasonal swing is why the dispatch plate stamps a season code for this airline alone.
