Across the year
UA 682 quarter by quarter

Share of 360 completed flights by arrival against schedule.
12 of 82 late departures made up the time and arrived on time, 15% of them. In the other direction, 24 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 DEN.
The worst days
Worst days for UA 682
The latest arrival of the period was on 10 August 2026, 4 hours 48 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. Four of the five worst days fell in August 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 10 August 2026 | 4 hours 48 minutes | Late-arriving aircraft |
| 3 August 2026 | 4 hours 11 minutes | National Airspace System |

Delay causes
Why UA 682 runs late
National Airspace System accounts for 52% of the 5,756 delay minutes carriers reported here, and the remaining four split what is left.
- 52%National Airspace System
- 37%Late-arriving aircraft
- 11%Carrier
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,756 reported delay minutes here, that single category outweighs weather by 37 to one. The split is drawn from 5,756 delay minutes reported on UA 682.
Cancellations are rare at 0.83%, 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
8.6% of arrivals land an hour or more late, close to the national 8.3%, so 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 853 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on three other city pairs in the data, including SFO to SAN (55), DEN to MCI (31) and SFO to SMF (1), but none flew often enough under UA 682 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SAN to DEN only.
One caution: this is a thin sample. 363 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 682
