Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s UA 495, check with United Airlines.

UA 495 lands a B+, 5 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 a little over an hour on average. That is a workable record, not a spotless one. That rests on 310 flights, with a median arrival 6 minutes early.

Set against the rest of the country, UA 495's record is 5 points better than the US average of 77.6%. That gap is worth roughly 49 fewer late arrivals for every thousand flights.

These figures cover 310 flights between July 2025 and June 2026. The median arrival is 6 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 495 flies

UA 495 flies IAD to DEN without a single fixed slot. Its most common scheduled departure was 22:10, used on 67 of 310 flights, with 22:34 (49 flights) and 22:35 (43 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 22:10 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and UA 495 runs 12 points better at 82.5%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

UA 495 next to IAD to DEN

Every carrier on IAD to DEN combined arrived on time 81.7% of the time across 3,560 flights, so UA 495 is about level with it. United flew 2,798 flights on the same city pair under all its flight numbers, including this one, and those ran 83.2% on time. Across its whole network United Airlines managed 79.0%, which this flight beats by 4 points.

Across the year

UA 495 quarter by quarter

UA 495 did not run the same all year. Its best quarter was Apr–Jun 2026 at 89.0% on time and its weakest Jul–Sep 2025 at 70.9%, a swing of 18 points on roughly 78 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 495 did best on Saturday at 90.9% on time and worst on Thursday at 73.9%. Each day rests on about 44 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 495 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 53% of the 3,820 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.

53% 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 3,820 reported delay minutes here, that single category outweighs weather by 12 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 3,820 delay minutes reported on UA 495.

Cancellations are rare at 0.32%, below the national 1.81% 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

6.5% 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 a little over an hour, which a normal layover absorbs.

The 1,452 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 four other city pairs in the data, including BNA to IAD (57), BDL to IAD (36) and SFO to TPA (6), but none flew often enough under UA 495 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAD to DEN only.

One caution: this is a thin sample. 310 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 495

For a booking, read UA 495 as 82.5% on time with 0.32% cancelled over 310 flights. Those are rates from the past twelve months, not a forecast for any particular day.
