Across the year
UA 2410 quarter by quarter
UA 2410 did not run the same all year. Its best quarter was Oct–Dec 2025 at 84.0% on time and its weakest Jul–Sep 2026 at 50.0%, a swing of 34 points on roughly 67 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.

Share of 332 completed flights by arrival against schedule.
11 of 65 late departures made up the time and arrived on time, 17% of them. In the other direction, 21 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SLC.
The worst days
Worst days for UA 2410
The latest arrival of the period was on 21 July 2026, 13 hours behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 21 July 2026 | 13 hours | Late-arriving aircraft |
| 11 June 2026 | 6 hours 31 minutes | Carrier |
| 7 August 2026 | 5 hours 52 minutes | Late-arriving aircraft |

Delay causes
Why UA 2410 runs late
Late-arriving aircraft accounts for 48% of the 7,931 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 25%Carrier
- 14%National Airspace System
- 13%Extreme weather
Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.2 times the usual weather exposure. The split is drawn from 7,931 delay minutes reported on UA 2410.
Cancellations sit at 1.19% against a national 1.89%, which is ordinary. Diversions add another 0.30%.
Connections and routes
What a delay on this flight costs
10.2% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 1,827 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The same number turns up on four other city pairs in the data, including TPA to IAD (24), LAS to IAH (16) and PDX to SFO (4), but none flew often enough under UA 2410 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAD to SLC only.
One caution: this is a thin sample. 337 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 2410
