| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 March 2026 | 5 hours 13 minutes | Late-arriving aircraft |
| 12 March 2026 | 4 hours 1 minute | Carrier |
| 21 August 2026 | 3 hours 36 minutes | Late-arriving aircraft |

Delay causes
Why UA 2132 runs late
Late-arriving aircraft accounts for 58% of the 6,436 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 6,436 reported delay minutes here, that single category outweighs weather by 58 to one. The split is drawn from 6,436 delay minutes reported on UA 2132.
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
10.8% 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 909 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 five other city pairs in the data, including SMF to EWR (122), SNA to DEN (82) and TYS to DEN (31), but none flew often enough under UA 2132 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to SMF only.
One caution: this is a thin sample. 343 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 2132
For a booking, read UA 2132 as 70.6% on time with 0.00% cancelled over 343 flights. Those are rates from the past twelve months, not a forecast for any particular day.
