These figures cover 353 flights between July 2025 and June 2026. Beyond the headline rate, 13.3% 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 2077 flies

UA 2077 flies EUG to SFO without a single fixed slot. Its most common scheduled departure was 14:09, used on 102 of 353 flights, with 13:57 (68 flights) and 14:02 (49 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 14:09 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and UA 2077 runs 10 points worse at 62.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 2077 quarter by quarter

UA 2077 did not run the same all year. Its best quarter was Jan–Mar 2026 at 76.9% on time and its weakest Apr–Jun 2026 at 33.0%, a swing of 44 points on roughly 88 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 2077 did best on Tuesday at 74.5% on time and worst on Sunday at 53.8%. Each day rests on about 50 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2077 runs late

One category carries most of the weight here. National Airspace System accounts for 50% of the 8,335 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
50%
Late-arriving aircraft
30%
Carrier
20%

50% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 4,186 minutes out of 8,335, against a national NAS share of 21%. The split is drawn from 8,335 delay minutes reported on UA 2077.

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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.3% 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.

The same number turns up on four other city pairs in the data, including SFO to DFW (65), SFO to ORD (26) and SFO to CLE (11), but none flew often enough under UA 2077 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EUG to SFO only.

One caution: this is a thin sample. 353 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 2077

For a booking, UA 2077 is a flight to put a long connection behind. 13.3% 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.
