These figures cover 327 flights between September 2025 and August 2026. The median arrival is 12 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule
When UA 687 flies
UA 687 is scheduled to leave Durango (DRO) at 07:00 local time and reach Denver (DEN) at 08:22. That slot held for 272 of the 327 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 687 runs level with that at 89.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

The worst days
Worst days for UA 687
The latest arrival of the period was on 17 January 2026, 4 hours 1 minute behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 January 2026 | 4 hours 1 minute | Carrier |
| 3 April 2026 | 3 hours 27 minutes | National Airspace System |
| 6 February 2026 | 2 hours 28 minutes | Carrier |

Delay causes
Why UA 687 runs late
Carrier accounts for 55% of the 1,875 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 44%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,034 of the 1,875 delay minutes reported here. The split is drawn from 1,875 delay minutes reported on UA 687.
Cancellations are rare at 0.31%, 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
Badly late arrivals are rare here: only 2.5% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The same number turns up on five other city pairs in the data, including DEN to IAD (45), DEN to LAS (31) and DEN to PSP (21), but none flew often enough under UA 687 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DRO to DEN only.
One caution: this is a thin sample. 327 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 687
For a booking, UA 687 has one of the better records a US domestic flight can show: 89.6% on time and 0.31% cancelled. That is a base rate, not a promise about any single day.
