Delay causes
Why UA 2254 runs late
Late-arriving aircraft accounts for 64% of the 5,129 delay minutes carriers reported here, and the remaining four split what is left.
- 64%Late-arriving aircraft
- 16%Carrier
- 14%National Airspace System
- 6%Extreme weather
64% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,129 reported delay minutes here, that single category outweighs weather by 12 to one. The split is drawn from 5,129 delay minutes reported on UA 2254.
Cancellations sit at 1.15% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
10.1% 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 1,671 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 three other city pairs in the data, including PDX to DEN (103), DEN to TPA (36) and ABQ to DEN (35), but none flew often enough under UA 2254 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to BDL only.
One caution: this is a thin sample. 260 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 2254
