These figures cover 271 flights between July 2025 and June 2026. Beyond the headline rate, 14.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When UA 2655 flies
UA 2655 flies DFW to DEN without a single fixed slot. Its most common scheduled departure was 16:45, used on 72 of 271 flights, with 16:50 (64 flights) and 16:40 (36 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 16:45 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and UA 2655 runs 8 points worse at 64.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
UA 2655 quarter by quarter
UA 2655 did not run the same all year. Its best quarter was Oct–Dec 2025 at 77.3% on time and its weakest Jul–Sep 2025 at 49.4%, a swing of 28 points on roughly 90 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 2655 did best on Sunday at 75.7% on time and worst on Wednesday at 57.5%. Each day rests on about 39 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2655 runs late
One category carries most of the weight here. National Airspace System accounts for 46% of the 7,272 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.
- 46%National Airspace System
- 43%Late-arriving aircraft
- 8%Carrier
- 3%Extreme weather
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 7,272 reported delay minutes here, that single category outweighs weather by 14 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 7,272 delay minutes reported on UA 2655.
Cancellations sit at 1.11% against a national 1.81%, which is ordinary. Diversions add another 1.11%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 14.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 641 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on five other city pairs in the data, including MRY to LAX (40), IAD to LAX (31) and PHL to ORD (19), but none flew often enough under UA 2655 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to DEN only.
One caution: this is a thin sample. 271 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 2655
For a booking, UA 2655 is a flight to put a long connection behind. 14.0% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
