These figures cover 364 flights between September 2025 and August 2026. The median arrival is 15 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.

The latest arrival of the period was on 24 January 2026, 2 hours 58 minutes 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 |
|---|---|---|
| 24 January 2026 | 2 hours 58 minutes | Late-arriving aircraft |
| 19 May 2026 | 2 hours 47 minutes | Carrier |
| 28 June 2026 | 2 hours 17 minutes | Late-arriving aircraft |
| 3 March 2026 | 1 hour 17 minutes | National Airspace System |

Delay causes
Why UA 2316 runs late
Late-arriving aircraft accounts for 53% of the 1,133 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 34%National Airspace System
- 13%Carrier
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,133 reported delay minutes here, that single category outweighs weather by 53 to one. The split is drawn from 1,133 delay minutes reported on UA 2316.
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 1.6% 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 628 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 six other city pairs in the data, including LAS to LAX (108), LAS to ORD (36) and SAT to DEN (23), but none flew often enough under UA 2316 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to LAS only.
One caution: this is a thin sample. 364 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 2316
For a booking, UA 2316 has one of the better records a US domestic flight can show: 94.2% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
