Other routes AS189 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| SEA→PHX Seattle to Phoenix | 2024-10-03 – 2025-06-11 | 153 | 76.0% |

Data and methodology
Calculated by FlyerIntel from 738 records of AS189 operating SEA → ANC, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
