These figures cover 290 flights between July 2025 and June 2026. Beyond the headline rate, 18.3% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When UA 2626 flies

UA 2626 flies SFO to EWR without a single fixed slot. Its most common scheduled departure was 16:10, used on 83 of 290 flights, with 16:20 (76 flights) and 16:40 (66 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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

A 16:10 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and UA 2626 runs 5 points worse at 67.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 2626 quarter by quarter

UA 2626 did not run the same all year. Its best quarter was Apr–Jun 2026 at 74.4% on time and its weakest Jul–Sep 2025 at 56.8%, a swing of 18 points on roughly 73 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 2626 did best on Friday at 80.4% on time and worst on Sunday at 55.8%. Each day rests on about 41 flights, so a gap of 25 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2626 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 72% of the 10,000 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.

Late-arriving aircraft
72%
Carrier
21%
National Airspace System
6%

72% 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 10,000 reported delay minutes here, that single category outweighs weather by 72 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 10,219 delay minutes reported on UA 2626.

Cancellations sit at 1.72% against a national 1.81%, which is ordinary. Diversions add another 0.34%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 18.3% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

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 two other city pairs in the data, including SDF to SFO (1) and DEN to TYS (1), but none flew often enough under UA 2626 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. 290 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 2626

For a booking, UA 2626 is a flight to put a long connection behind. 18.3% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
