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 2026 at 60.0%, a swing of 21 points on roughly 78 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 2324 did best on Saturday at 83.7% on time and worst on Thursday at 67.4%. Each day rests on about 44 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Share of 309 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 64 departures that left 15 minutes late or more, only 6 made it up before arrival. In the other direction, 23 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at CID.
The worst days
Worst days for UA 2324
The latest arrival of the period was on 28 December 2025, 14 hours 25 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across December, March, May and June, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 December 2025 | 14 hours 25 minutes | Extreme weather |
| 27 December 2025 | 13 hours 17 minutes | Extreme weather |
| 6 March 2026 | 5 hours 54 minutes | Late-arriving aircraft |

Delay causes
Why UA 2324 runs late
Late-arriving aircraft accounts for 46% of the 6,926 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 20%Carrier
- 18%Extreme weather
- 16%National Airspace System
Extreme weather accounts for 18% 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 2.9 times the usual weather exposure. The split is drawn from 6,926 delay minutes reported on UA 2324.
Cancellations are rare at 0.32%, 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
9.7% 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 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.
The same number turns up on four other city pairs in the data, including JAC to DEN (98), PHX to DEN (36) and IAD to ABQ (31), 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. 311 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
