| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 August 2026 | 6 hours 28 minutes | Late-arriving aircraft |
| 22 August 2026 | 5 hours 24 minutes | Late-arriving aircraft |

Delay causes
Why UA 1942 runs late
Late-arriving aircraft accounts for 62% of the 6,946 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Late-arriving aircraft
- 22%Carrier
- 14%National Airspace System
- 2%Extreme weather
62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,946 reported delay minutes here, that single category outweighs weather by 33 to one. The split is drawn from 6,946 delay minutes reported on UA 1942.
Cancellations are rare at 0.27%, 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
9.9% 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 775 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 EUG to DEN (159), MKE to DEN (58) and SFO to DEN (24), but none flew often enough under UA 1942 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to AUS only.
One caution: this is a thin sample. 364 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 1942
For a booking, read UA 1942 as 73.5% on time with 0.27% cancelled over 364 flights. Those are rates from the past twelve months, not a forecast for any particular day.
