Delay causes
Why UA 1565 runs late

- 54%Late-arriving aircraft
- 24%National Airspace System
- 21%Carrier
- 1%Extreme weather
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,218 reported delay minutes here, that single category outweighs weather by 38 to one. The split is drawn from 8,218 delay minutes reported on UA 1565.
Cancellations sit at 1.21% against a national 1.89%, which is ordinary. Diversions add another 0.30%.
Connections and routes
What a delay on this flight costs
14.1% 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.
The 641 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 three other city pairs in the data, including SAN to DEN (169), ORD to CLE (28) and MEM to DEN (19), but none flew often enough under UA 1565 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to DFW only.
One caution: this is a thin sample. 331 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 1565
For a booking, UA 1565 is a flight to put a long connection behind. 14.1% 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.
