Across the year
UA 680 quarter by quarter
UA 680 did not run the same all year. Its best quarter was Oct–Dec 2025 at 80.2% on time and its weakest Jul–Sep 2026 at 49.2%, a swing of 31 points on roughly 85 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 680 did best on Wednesday at 75.0% on time and worst on Friday at 59.2%. Each day rests on about 48 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Share of 337 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 77 departures that left 15 minutes late or more, only 9 made it up before arrival. In the other direction, 44 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ORF.
The worst days
Worst days for UA 680
The latest arrival of the period was on 28 July 2026, 3 hours 47 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 July 2026 | 3 hours 47 minutes | Late-arriving aircraft |
| 14 August 2026 | 3 hours 28 minutes | Late-arriving aircraft |
| 6 March 2026 | 3 hours 15 minutes | Late-arriving aircraft |
| 29 December 2025 | 3 hours 11 minutes | Late-arriving aircraft |
| 29 July 2026 | 3 hours 8 minutes | Late-arriving aircraft |
Delay causes
Why UA 680 runs late
Late-arriving aircraft accounts for 42% of the 5,945 delay minutes carriers reported here, and the remaining four split what is left.
- 42%Late-arriving aircraft
- 32%National Airspace System
- 23%Carrier
- 2%Extreme weather
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,945 reported delay minutes here, that single category outweighs weather by 23 to one. The split is drawn from 5,945 delay minutes reported on UA 680.
Cancellations are rare at 0.59%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
9.2% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 1,553 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 three other city pairs in the data, including PSP to DEN (37), FCA to DEN (24) and SFO to CLE (1), but none flew often enough under UA 680 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to ORF only.
One caution: this is a thin sample. 339 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 680
