Historical statistics for July 2025 to June 2026, not live status. For today’s UA 2132, check with United Airlines.
UA 2132 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 325 flights, with a median arrival 1 minute late.
The national on-time rate over the same period is 77.6%, so UA 2132 runs 6 points behind the country as a whole. Across a thousand flights that is about 60 extra late arrivals.

These figures cover 325 flights between July 2025 and June 2026. Beyond the headline rate, 9.6% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When UA 2132 flies
UA 2132 flies DEN to SMF without a single fixed slot. Its most common scheduled departure was 19:15, used on 86 of 325 flights, with 19:20 (50 flights) and 19:37 (41 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 19:15 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 2132 runs 3 points better at 71.6%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
UA 2132 quarter by quarter
UA 2132 did not run the same all year. Its best quarter was Oct–Dec 2025 at 83.5% on time and its weakest Jul–Sep 2025 at 57.5%, a swing of 26 points on roughly 81 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, UA 2132 did best on Wednesday at 80.9% on time and worst on Saturday at 65.2%. Each day rests on about 46 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2132 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 56% of the 5,780 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 56%Late-arriving aircraft
- 34%Carrier
- 9%National Airspace System
- 0%Extreme weather
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,780 reported delay minutes here, that single category outweighs weather by 56 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,780 delay minutes reported on UA 2132.
Cancellations are rare at 0.31%, below the national 1.81% 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.6% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on six other city pairs in the data, including SMF to EWR (143), SNA to DEN (41) and TUS 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. 325 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 71.6% on time with 0.31% cancelled over 325 flights. Those are rates from the past twelve months, not a forecast for any particular day.
