Historical statistics for July 2025 to June 2026, not live status. For today’s UA 514, check with United Airlines.
UA 514 lands a B, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 295 flights, with a median arrival 3 minutes early.

These figures cover 295 flights between July 2025 and June 2026. Beyond the headline rate, 8.0% 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 514 flies
UA 514 flies CID to DEN without a single fixed slot. Its most common scheduled departure was 15:16, used on 41 of 295 flights, with 16:33 (36 flights) and 15:10 (35 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 15:16 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and UA 514 runs 4 points better at 76.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
UA 514 quarter by quarter
UA 514 did not run the same all year. Its best quarter was Oct–Dec 2025 at 84.4% on time and its weakest Jul–Sep 2025 at 56.5%, a swing of 28 points on roughly 74 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.

- Jan–Mar 202689 flights84.3%

By weekday, UA 514 did best on Thursday at 84.6% on time and worst on Saturday at 67.5%. Each day rests on about 42 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 514 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 44% of the 5,979 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.
- 44%Late-arriving aircraft
- 25%National Airspace System
- 24%Carrier
- 7%Extreme weather
44% 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 5,979 reported delay minutes here, that single category outweighs weather by 6 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 5,979 delay minutes reported on UA 514.
Cancellations sit at 1.02% against a national 1.81%, which is ordinary. Diversions add another 1.02%.
Connections and routes
What a delay on this flight costs
8.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
The 692 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 five other city pairs in the data, including DEN to SDF (56), BUF to ORD (37) and DEN to DCA (31), but none flew often enough under UA 514 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CID to DEN only.
One caution: this is a thin sample. 295 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 514
For a booking, read UA 514 as 76.8% on time with 1.02% cancelled over 295 flights. Those are rates from the past twelve months, not a forecast for any particular day.
