These figures cover 284 flights between July 2025 and June 2026. Beyond the headline rate, 8.5% 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 2324 flies
UA 2324 flies DEN to CID without a single fixed slot. Its most common scheduled departure was 17:55, used on 81 of 284 flights, with 17:37 (41 flights) and 17:33 (37 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 17:55 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 2324 runs 7 points better at 74.8%. 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 2324 quarter by quarter
UA 2324 did not run the same all year. Its best quarter was Jan–Mar 2026 at 80.9% on time and its weakest Jul–Sep 2025 at 54.1%, a swing of 27 points on roughly 71 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.

Scale runs 45% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, UA 2324 did best on Saturday at 85.0% on time and worst on Sunday at 67.5%. Each day rests on about 41 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2324 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 6,265 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.
- 46%Late-arriving aircraft
- 20%Extreme weather
- 20%Carrier
- 15%National Airspace System
Extreme weather accounts for 20% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.1 times the usual weather exposure. The split is drawn from 6,265 delay minutes reported on UA 2324.
Cancellations are rare at 0.35%, 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
8.5% 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 four other city pairs in the data, including JAC to DEN (98), RNO to DEN (49) and PHX to DEN (36), but none flew often enough under UA 2324 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to CID only.
One caution: this is a thin sample. 284 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 2324
For a booking, read UA 2324 as 74.8% on time with 0.35% cancelled over 284 flights. Those are rates from the past twelve months, not a forecast for any particular day.
