Across the year
UA 1300 quarter by quarter

| 30 June 2026 | 4 hours 58 minutes | Late-arriving aircraft |

Delay causes
Why UA 1300 runs late
Late-arriving aircraft accounts for 63% of the 7,366 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Late-arriving aircraft
- 25%National Airspace System
- 11%Carrier
- 1%Extreme weather
63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,366 reported delay minutes here, that single category outweighs weather by 58 to one. The split is drawn from 7,366 delay minutes reported on UA 1300.
Cancellations are rare at 0.62%, 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
13.4% 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 1,013 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 BUR to SFO (21), MCO to DEN (19) and SFO to ABQ (15), but none flew often enough under UA 1300 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to BNA only.
One caution: this is a thin sample. 323 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 1300
For a booking, UA 1300 is a flight to put a long connection behind. 13.4% 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.
