| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 May 2026 | 5 hours 31 minutes | Carrier |
| 18 June 2026 | 3 hours 25 minutes | Late-arriving aircraft |
| 26 October 2025 | 3 hours 14 minutes | Carrier |

Delay causes
Why UA 1995 runs late
Late-arriving aircraft accounts for 48% of the 4,972 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 29%National Airspace System
- 23%Carrier
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,972 reported delay minutes here, that single category outweighs weather by 48 to one. The split is drawn from 4,972 delay minutes reported on UA 1995.
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
9.3% 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.
The same number turns up on four other city pairs in the data, including LAS to EWR (72), LAS to ORD (16) and LAS to IAD (4), but none flew often enough under UA 1995 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SFO to LAS only.
One caution: this is a thin sample. 357 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 1995
