Noon to 3 PM: 88% of flights arrived on time, against 77% for departures 3 to 6 PM.
Which airline is most on time from FAI to SEA?
Alaska, with a season-adjusted 83% chance of operating and arriving on time over 1,858 flights. The adjustment compares each airline with what the route did in the months it flew, so a carrier that skipped a stormy month gets no free credit.

December (72% on time); the best was April (89%), averaged over Jun 2023 to May 2026.
Is this a prediction for my flight?
No. These are historical odds from the US DOT on-time reports, FAA advisories and airport weather records. Check your flight status and the FAA delay board on the day you fly.
