Other routes AS490 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→SLC Seattle to Salt Lake City | 2026-03-07 – 2026-03-07 | 1 | — |
| SAN→BOI San Diego to Boise | 2026-01-07 – 2026-02-11 | 36 | — |
Because the same number has served different journeys, the statistics above describe only the route AS490 currently operates. Blending them would produce an average of two different flights.
Data and methodology
Calculated by FlyerIntel from 800 records of AS490 operating SEA → MSY, 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.
