These figures cover 297 flights between July 2025 and June 2026. The median arrival is 17 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 2610 flies

UA 2610 flies LAX to DEN without a single fixed slot. Its most common scheduled departure was 19:03, used on 71 of 297 flights, with 18:45 (68 flights) and 19:00 (45 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 19:03 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 2610 runs 24 points better at 91.8%. 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 2610 next to LAX to DEN

Across the year

UA 2610 quarter by quarter

Quarter by quarter UA 2610 held fairly steady: 93.4% in Oct–Dec 2025, 91.0% in Jan–Mar 2026 and 91.8% in Apr–Jun 2026. A spread of 2 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, UA 2610 did best on Saturday at 100.0% on time and worst on Wednesday at 85.7%. Each day rests on about 42 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2610 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 78% of the 1,328 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.

Late-arriving aircraft
78%
Carrier
13%
National Airspace System

78% 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 1,328 reported delay minutes here, that single category outweighs weather by 78 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 1,328 delay minutes reported on UA 2610.

Cancellations are rare at 0.34%, 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

Badly late arrivals are rare here: only 2.0% 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 862 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 eight other city pairs in the data, including SFO to LAX (117), LAS to LAX (68) and DEN to BOS (61), but none flew often enough under UA 2610 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to DEN only.

One caution: this is a thin sample. 297 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 2610

For a booking, UA 2610 has one of the better records a US domestic flight can show: 91.8% on time and 0.34% cancelled. That is a base rate, not a promise about any single day.
