| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 March 2026 | 4 hours 26 minutes | Late-arriving aircraft |
| 4 July 2026 | 4 hours 14 minutes | Late-arriving aircraft |

Delay causes
Why UA 1482 runs late
Late-arriving aircraft accounts for 57% of the 4,460 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 34%National Airspace System
- 9%Carrier
- 1%Extreme weather
57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,460 reported delay minutes here, that single category outweighs weather by 57 to one. The split is drawn from 4,460 delay minutes reported on UA 1482.
Cancellations are rare at 0.36%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
9.7% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 1,846 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
UA 1482 is not only a SFO to ORD flight. It also flew SEA to SFO (256 flights, 66.3% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 274 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.
