AS delay-share reading
Across 1,292,316 BTS-reported flights (2020–2025), Alaska Airlines posts 80.8% on-time, 1.8 points above the 79% national flight-weighted average, with 248,598 delayed arrivals and 24,678 cancellations (1.91% of the book). When a flight runs late, the average delay is 56.5 minutes.
Delay minutes concentrate in Late Aircraft (37.1% late-aircraft, 30.9% carrier, 27.5% NAS, 3.9% weather, 0.6% security across 12,490,439 total delay minutes). That mix is this carrier’s fingerprint, not a fleet-wide template sentence.
On the multi-year calendar, AS is strongest in October (84.4% on-time on about 18,269 flights per month) and weakest in December (75.9%). The 8.5-point seasonal swing is why the dispatch plate stamps a season code for this airline alone.
