G4 delay-share reading
Across 694,895 BTS-reported flights (2020–2025), Allegiant Air posts 75.3% on-time, 3.7 points below the 79% national flight-weighted average, with 171,495 delayed arrivals and 25,650 cancellations (3.69% of the book). When a flight runs late, the average delay is 81.5 minutes.
Delay minutes concentrate in Late Aircraft (40.2% late-aircraft, 31.6% carrier, 18.9% NAS, 8.8% weather, 0.4% security across 13,258,817 total delay minutes). That mix is this carrier’s fingerprint, not a fleet-wide template sentence.
On the multi-year calendar, G4 is strongest in September (80.2% on-time on about 6,557 flights per month) and weakest in July (68.5%). The 11.7-point seasonal swing is why the dispatch plate stamps a season code for this airline alone.
