These figures cover 314 flights between July 2025 and June 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 flies DRO to DEN without a single fixed slot. Its most common scheduled departure was 07:00, used on 210 of 314 flights, with 07:05 (103 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 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 2 points worse at 87.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

UA 687 quarter by quarter

UA 687 did not run the same all year. Its best quarter was Jan–Mar 2026 at 92.8% on time and its weakest Jul–Sep 2025 at 76.3%, a swing of 17 points on roughly 79 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 687 ranged from 82.2% on Sunday to 93.2% on Wednesday. With about 45 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 687 runs late

One category carries most of the weight here. Carrier accounts for 62% of the 2,853 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.

  • Carrier
    62%
  • National Airspace System
    33%
  • Late-arriving aircraft
    4%
  • Extreme weather
    1%

The largest share of delay minutes, 62%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,767 of the 2,853 delay minutes reported here. The split is drawn from 2,853 delay minutes reported on UA 687.

Cancellations sit at 0.96% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.5% land an hour or more behind schedule, against 8.1% 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 four other city pairs in the data, including DEN to IAD (45), DEN to LAS (31) and EWR to CHS (16), 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. 314 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: 87.1% on time and 0.96% cancelled. That is a base rate, not a promise about any single day.
