Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1149, check with United Airlines.

UA 1149 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 347 flights, with a median arrival 21 minutes early.

Set against the rest of the country, UA 1149's record is 13 points better than the US average of 77.6%. That gap is worth roughly 127 fewer late arrivals for every thousand flights.

These figures cover 347 flights between July 2025 and June 2026. The median arrival is 21 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 15:25. That slot held for 322 of the 347 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

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 90.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

UA 1149 next to SFO to EWR

Every carrier on SFO to EWR combined arrived on time 76.4% of the time across 4,401 flights, so UA 1149 is 14 points ahead of it. United flew 3,790 flights on the same city pair under all its flight numbers, including this one, and those ran 74.8% on time. Across its whole network United Airlines managed 79.0%, which this flight beats by 11 points.

Across the year

UA 1149 quarter by quarter

UA 1149 did not run the same all year. Its best quarter was Jan–Mar 2026 at 95.5% on time and its weakest Jul–Sep 2025 at 84.3%, a swing of 11 points on roughly 87 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, UA 1149 did best on Friday at 97.9% on time and worst on Monday at 80.9%. Each day rests on about 50 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1149 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 43% of the 2,811 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 2,811 reported delay minutes here, that single category outweighs weather by 43 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 2,811 delay minutes reported on UA 1149.

Cancellations sit at 1.44% against a national 1.81%, which is ordinary. Diversions add another 0.86%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.1% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

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 seven other city pairs in the data, including EWR to MSY (57), EWR to CLT (35) and EWR to RSW (24), 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. 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 1149

For a booking, UA 1149 has one of the better records a US domestic flight can show: 90.3% on time and 1.44% cancelled. That is a base rate, not a promise about any single day.
