These figures cover 334 flights between September 2025 and August 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.

Across the year
UA 2610 quarter by quarter
UA 2610 did not run the same all year. Its best quarter was Oct–Dec 2025 at 93.4% on time and its weakest Jul–Sep 2026 at 83.3%, a swing of 10 points on roughly 84 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.

The latest arrival of the period was on 20 July 2026, 4 hours 23 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 July 2026 | 4 hours 23 minutes | Late-arriving aircraft |
| 28 November 2025 | 3 hours 6 minutes | Late-arriving aircraft |
| 14 August 2026 | 2 hours 23 minutes | National Airspace System |
| 3 June 2026 | 2 hours 19 minutes | Late-arriving aircraft |

Delay causes
Why UA 2610 runs late
Late-arriving aircraft accounts for 63% of the 2,147 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Late-arriving aircraft
- 22%National Airspace System
- 15%Carrier
63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,147 reported delay minutes here, that single category outweighs weather by 63 to one. The split is drawn from 2,147 delay minutes reported on UA 2610.
Cancellations are rare at 0.00%, below the national 1.89% 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
Badly late arrivals are rare here: only 3.3% land an hour or more behind schedule, against 8.3% 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.
The same number turns up on eight other city pairs in the data, including SFO to LAX (177), ORD to SFO (91) and LAS to LAX (55), 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. 334 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: 90.7% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
