These figures cover 322 flights between July 2025 and June 2026. The median arrival is 5 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 1763 flies

UA 1763 flies SAN to SFO without a single fixed slot. Its most common scheduled departure was 13:50, used on 49 of 322 flights, with 13:39 (41 flights) and 12:49 (37 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 13:50 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 1763 runs 4 points worse at 75.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 1763 quarter by quarter

UA 1763 did not run the same all year. Its best quarter was Jan–Mar 2026 at 90.2% on time and its weakest Apr–Jun 2026 at 63.7%, a swing of 27 points on roughly 81 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 1763 did best on Tuesday at 87.5% on time and worst on Thursday at 64.4%. Each day rests on about 46 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1763 runs late

One category carries most of the weight here. National Airspace System accounts for 44% of the 4,848 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.

  • National Airspace System
    44%
  • Late-arriving aircraft
    42%
  • Carrier
    14%

42% 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 4,848 reported delay minutes here, that single category outweighs weather by 42 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 4,848 delay minutes reported on UA 1763.

Cancellations are rare at 0.00%, below the national 1.81% 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

7.8% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

The same number turns up on seven other city pairs in the data, including SFO to SEA (53), SFO to ORD (46) and SEA to ORD (37), but none flew often enough under UA 1763 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SAN to SFO only.

One caution: this is a thin sample. 322 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 1763

For a booking, read UA 1763 as 75.2% on time with 0.00% cancelled over 322 flights. Those are rates from the past twelve months, not a forecast for any particular day.
