These figures cover 263 flights between September 2025 and August 2026. The median arrival is 6 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 1806 runs late
Carrier accounts for 57% of the 4,501 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Carrier
- 37%Late-arriving aircraft
- 7%National Airspace System
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,501 reported delay minutes here, that single category outweighs weather by 37 to one. The split is drawn from 4,501 delay minutes reported on UA 1806.
Cancellations sit at 1.14% against a national 1.89%, which is ordinary. Diversions add another 0.38%.
Connections and routes
What a delay on this flight costs
6.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
At 3,365 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 seven other city pairs in the data, including DFW to EWR (32), ORD to OMA (32) and BOS to EWR (20), but none flew often enough under UA 1806 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to HNL to DEN only.
One caution: this is a thin sample. 263 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
