Delay causes
Why UA 1417 runs late
Late-arriving aircraft accounts for 45% of the 6,298 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 38%Carrier
- 10%Extreme weather
- 7%National Airspace System
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,298 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 6,298 delay minutes reported on UA 1417.
Cancellations are rare at 0.32%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
10.5% 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.
The same number turns up on seven other city pairs in the data, including FLL to DEN (144), ONT to DEN (83) and DEN to RDU (55), but none flew often enough under UA 1417 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to BIL only.
One caution: this is a thin sample. 308 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 1417
For a booking, read UA 1417 as 75.5% on time with 0.32% cancelled over 308 flights. Those are rates from the past twelve months, not a forecast for any particular day.
