These figures cover 365 flights between September 2025 and August 2026. The median arrival is 9 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.

Delay causes
Why UA 2307 runs late
Carrier accounts for 53% of the 3,455 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Carrier
- 35%Late-arriving aircraft
- 12%National Airspace System
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,455 reported delay minutes here, that single category outweighs weather by 35 to one. The split is drawn from 3,455 delay minutes reported on UA 2307.
Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 0.27%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.4% 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.
At 3,414 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 five other city pairs in the data, including PHL to DEN (47), IAH to DEN (36) and OKC to DEN (35), but none flew often enough under UA 2307 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to LIH only.
One caution: this is a thin sample. 365 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 2307
For a booking, UA 2307 has one of the better records a US domestic flight can show: 85.0% on time and 1.10% cancelled. That is a base rate, not a promise about any single day.
