These figures cover 342 flights between September 2025 and August 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

The worst days
Worst days for OO 5024
The latest arrival of the period was on 14 August 2026, 4 hours 50 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across August, December, May, September and July, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 August 2026 | 4 hours 50 minutes | Extreme weather |
| 19 December 2025 | 3 hours 54 minutes | Extreme weather |
| 7 May 2026 | 3 hours 52 minutes | Carrier |

Delay causes
Why OO 5024 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,522 reported delay minutes.
- 39%Late-arriving aircraft
- 30%Carrier
- 19%Extreme weather
- 12%National Airspace System
Extreme weather accounts for 19% 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 3,522 delay minutes reported on OO 5024.
Cancellations are rare at 0.88%, 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
5.0% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
The same number turns up on three other city pairs in the data, including DEN to CYS (62), DEN to SHR (32) and DEN to COD (1), but none flew often enough under OO 5024 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CYS to DEN only.
One caution: this is a thin sample. 342 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 OO 5024
For a booking, read OO 5024 as 84.9% on time with 0.88% cancelled over 342 flights. Those are rates from the past twelve months, not a forecast for any particular day.
