Historical statistics for July 2025 to June 2026, not live status. For today’s UA 2154, check with United Airlines.
UA 2154 lands a B+, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 316 flights, with a median arrival 8 minutes early.
Set against the rest of the country, UA 2154's record is 6 points better than the US average of 77.6%. That gap is worth roughly 58 fewer late arrivals for every thousand flights.

These figures cover 316 flights between July 2025 and June 2026. The median arrival is 8 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 2154 flies
UA 2154 flies DEN to BUR without a single fixed slot. Its most common scheduled departure was 11:15, used on 84 of 316 flights, with 11:20 (69 flights) and 11:31 (37 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 11:15 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 2154 runs 5 points better at 83.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
UA 2154 quarter by quarter
Quarter by quarter UA 2154 held fairly steady: 88.4% in Jul–Sep 2025, 84.4% in Oct–Dec 2025, 84.4% in Jan–Mar 2026 and 79.1% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, UA 2154 did best on Saturday at 88.9% on time and worst on Wednesday at 73.3%. Each day rests on about 45 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2154 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 61% of the 3,081 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.
- 61%Late-arriving aircraft
- 20%National Airspace System
- 19%Carrier
61% 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 3,081 reported delay minutes here, that single category outweighs weather by 61 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 3,081 delay minutes reported on UA 2154.
Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
5.1% 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 about an hour, which a normal layover absorbs.
The 850 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 eleven other city pairs in the data, including ORD to ROC (48), MSY to ORD (48) and BUR to SFO (45), but none flew often enough under UA 2154 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to BUR only.
One caution: this is a thin sample. 316 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 2154
For a booking, read UA 2154 as 83.4% on time with 0.00% cancelled over 316 flights. Those are rates from the past twelve months, not a forecast for any particular day.
