These figures cover 260 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Delay causes
Why UA 1306 runs late
Late-arriving aircraft accounts for 58% of the 2,908 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Late-arriving aircraft
- 31%Carrier
- 11%National Airspace System
58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,908 reported delay minutes here, that single category outweighs weather by 58 to one. The split is drawn from 2,908 delay minutes reported on UA 1306.
Cancellations sit at 1.54% against a national 1.89%, which is ordinary. Diversions add another 0.38%.
Connections and routes
What a delay on this flight costs
5.5% 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 roughly 45 minutes, which a normal layover absorbs.
The same number turns up on seven other city pairs in the data, including TVC to DEN (102), SRQ to DEN (32) and DEN to IAH (31), but none flew often enough under UA 1306 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to JAC 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 1306
