These figures cover 342 flights between September 2025 and August 2026. The median arrival is 3 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Share of 341 completed flights by arrival against schedule.
13 of 61 late departures made up the time and arrived on time, 21% of them. In the other direction, 26 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at FLL.

|---|---|---|
| 3 December 2025 | 3 hours 15 minutes | Late-arriving aircraft |
| 28 July 2026 | 2 hours 57 minutes | Late-arriving aircraft |

Delay causes
Why UA 1374 runs late
Late-arriving aircraft accounts for 58% of the 4,059 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Late-arriving aircraft
- 21%National Airspace System
- 20%Carrier
- 1%Extreme weather
58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,059 reported delay minutes here, that single category outweighs weather by 58 to one. The split is drawn from 4,059 delay minutes reported on UA 1374.
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
6.7% 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 55 minutes, which a normal layover absorbs.
At 1,703 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The same number turns up on five other city pairs in the data, including TUS to DEN (52), SAT to SFO (24) and SFO to DEN (24), but none flew often enough under UA 1374 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to FLL only.
One caution: this is a thin sample. 342 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.
