OO delay-share reading

Across 4,343,656 BTS-reported flights (2020–2025), SkyWest Airlines posts 83.6% on-time, 4.6 points above the 79% national flight-weighted average, with 712,762 delayed arrivals and 80,320 cancellations (1.85% of the book). When a flight runs late, the average delay is 86.8 minutes.

Delay minutes concentrate in Carrier (21.1% late-aircraft, 53.7% carrier, 10.7% NAS, 14.3% weather, 0.2% security across 58,129,562 total delay minutes). That mix is this carrier’s fingerprint, not a fleet-wide template sentence.

On the multi-year calendar, OO is strongest in April (86.8% on-time on about 57,490 flights per month) and weakest in December (79.6%). The 7.2-point seasonal swing is why the dispatch plate stamps a season code for this airline alone.
