Historical statistics for July 2025 to June 2026, not live status. For today’s UA 790, check with United Airlines.

UA 790 lands a B+, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 356 flights, with a median arrival 10 minutes early.

Set against the rest of the country, UA 790's record is 5 points better than the US average of 77.6%. That gap is worth roughly 47 fewer late arrivals for every thousand flights.

These figures cover 356 flights between July 2025 and June 2026. Beyond the headline rate, 8.4% 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 790 flies

UA 790 flies SFO to EUG without a single fixed slot. Its most common scheduled departure was 10:35, used on 236 of 356 flights, with 10:25 (36 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 10:35 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 790 runs level with that at 82.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

UA 790 quarter by quarter

UA 790 did not run the same all year. Its best quarter was Jan–Mar 2026 at 86.9% on time and its weakest Apr–Jun 2026 at 76.1%, a swing of 11 points on roughly 89 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.

Jan–Mar 202684 flights86.9%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, UA 790 ranged from 76.1% on Wednesday to 86.5% on Friday. With about 51 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 790 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 5,243 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
45%
Carrier
44%
National Airspace System
11%

45% 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 5,243 reported delay minutes here, that single category outweighs weather by 45 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 5,243 delay minutes reported on UA 790.

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

8.4% 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 an hour and a half, which a normal layover absorbs.

The same number turns up on four other city pairs in the data, including DFW to SFO (222), ATL to SFO (37) and PIT to SFO (21), but none flew often enough under UA 790 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SFO to EUG only.

One caution: this is a thin sample. 356 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 790

For a booking, read UA 790 as 82.3% on time with 0.00% cancelled over 356 flights. Those are rates from the past twelve months, not a forecast for any particular day.
