Delay causes
Why UA 2745 runs late
Late-arriving aircraft accounts for 62% of the 6,058 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Late-arriving aircraft
- 33%Carrier
- 5%National Airspace System
- 1%Extreme weather
62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,058 reported delay minutes here, that single category outweighs weather by 62 to one. The split is drawn from 6,058 delay minutes reported on UA 2745.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
12.9% 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 948 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on seven other city pairs in the data, including GRR to DEN (179), DEN to RAP (90) and LAX to DEN (31), but none flew often enough under UA 2745 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to SJC only.
One caution: this is a thin sample. 256 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 2745
For a booking, UA 2745 is a flight to put a long connection behind. 12.9% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
