These figures cover 365 flights between September 2025 and August 2026. The median arrival is 20 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule
When UA 1149 flies
UA 1149 is scheduled to leave San Francisco (SFO) at 07:00 local time and reach Newark (EWR) at 15:49. That slot held for 340 of the 365 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 1149 runs level with that at 89.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

| 20 July 2026 | 9 hours | Late-arriving aircraft |
| 14 December 2025 | 7 hours 33 minutes | Late-arriving aircraft |

Delay causes
Why UA 1149 runs late
Late-arriving aircraft accounts for 62% of the 4,243 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Late-arriving aircraft
- 28%Carrier
- 10%National Airspace System
62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,243 reported delay minutes here, that single category outweighs weather by 62 to one. The split is drawn from 4,243 delay minutes reported on UA 1149.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 1.10%.
Connections and routes
What a delay on this flight costs
5.6% 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 close to two hours, which a normal layover absorbs.
At 2,565 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.
The same number turns up on five other city pairs in the data, including EWR to MSY (57), EWR to LAS (40) and EWR to CLT (35), but none flew often enough under UA 1149 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SFO to EWR only.
One caution: this is a thin sample. 365 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 1149
For a booking, UA 1149 has one of the better records a US domestic flight can show: 89.9% on time and 1.37% cancelled. That is a base rate, not a promise about any single day.
