Delay causes
Why UA 1790 runs late
Late-arriving aircraft accounts for 53% of the 4,979 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 26%National Airspace System
- 20%Carrier
- 1%Extreme weather
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,979 reported delay minutes here, that single category outweighs weather by 53 to one. The split is drawn from 4,979 delay minutes reported on UA 1790.
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
8.0% 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 about an hour, which a normal layover absorbs.
The 1,201 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.
UA 1790 is not only a DEN to CLE flight. It also flew SBA to DEN (256 flights, 73.5% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 287 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.
