Across the year
UA 790 quarter by quarter

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 May 2026 | 5 hours | Late-arriving aircraft |
| 16 May 2026 | 4 hours 52 minutes | Carrier |
| 4 January 2026 | 4 hours 17 minutes | Carrier |

Delay causes
Why UA 790 runs late
Late-arriving aircraft accounts for 49% of the 5,011 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 39%Carrier
- 13%National Airspace System
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,011 reported delay minutes here, that single category outweighs weather by 49 to one. The split is drawn from 5,011 delay minutes reported on UA 790.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
8.1% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
The same number turns up on five other city pairs in the data, including DFW to SFO (214), ATL to SFO (24) and SAT to SFO (21), but none flew often enough under UA 790 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SFO to EUG only.
One caution: this is a thin sample. 347 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking UA 790
For a booking, read UA 790 as 79.5% on time with 0.00% cancelled over 347 flights. Those are rates from the past twelve months, not a forecast for any particular day.
