Historical statistics for July 2025 to June 2026, not live status. For today’s UA 680, check with United Airlines.

UA 680 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 7 points worse than the national rate of 77.6%. The late ones land roughly 45 minutes behind schedule. That rests on 278 flights, with a median arrival 1 minute early.

The national on-time rate over the same period is 77.6%, so UA 680 runs 7 points behind the country as a whole. Across a thousand flights that is about 69 extra late arrivals.

These figures cover 278 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Schedule

When UA 680 flies

UA 680 flies DEN to ORF without a single fixed slot. Its most common scheduled departure was 17:30, used on 37 of 278 flights, with 17:50 (36 flights) and 17:55 (35 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 17:30 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 680 runs 3 points better at 70.7%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

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 Apr–Jun 2026 at 58.2%, a swing of 22 points on roughly 93 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 79.5% on time and worst on Saturday at 64.1%. Each day rests on about 40 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 680 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,795 reported delay minutes.

  • National Airspace System
    36%
  • Late-arriving aircraft
    34%
  • Carrier
    29%
  • Extreme weather
    1%

36% 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 1,361 minutes out of 3,795, against a national NAS share of 21%. The split is drawn from 3,795 delay minutes reported on UA 680.

Cancellations are rare at 0.72%, below the national 1.81% 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

7.2% 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 roughly 45 minutes, which a normal layover absorbs.

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 two other city pairs in the data, including FCA to DEN (86) and PSP to DEN (37), 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. 278 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

For a booking, read UA 680 as 70.7% on time with 0.72% cancelled over 278 flights. Those are rates from the past twelve months, not a forecast for any particular day.
