These figures cover 365 flights between September 2025 and August 2026. The median arrival is 23 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 2308 runs late
Late-arriving aircraft accounts for 47% of the 803 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 41%Carrier
- 13%National Airspace System
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 803 reported delay minutes here, that single category outweighs weather by 47 to one. The split is drawn from 803 delay minutes reported on UA 2308.
Cancellations sit at 2.47% against a national 1.89%, which is ordinary. Diversions add another 0.55%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.1% 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.
Every one of the 365 flights under UA 2308 in the data flew LIH to DEN. The number was not reused on any other city pair, which makes this a clean record of one route.
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.
