These figures cover 283 flights between September 2025 and August 2026. The median arrival is 13 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 latest arrival of the period was on 29 November 2025, 3 hours 57 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 29 November 2025 | 3 hours 57 minutes | Late-arriving aircraft |
| 1 November 2025 | 3 hours 35 minutes | Carrier |

Delay causes
Why OO 5808 runs late
Late-arriving aircraft accounts for 49% of the 3,167 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 39%Carrier
- 11%National Airspace System
- 1%Extreme weather
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,167 reported delay minutes here, that single category outweighs weather by 49 to one. The split is drawn from 3,167 delay minutes reported on OO 5808.
Cancellations are rare at 0.35%, 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
7.1% 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 one other city pair in the data, including ORD to SCE (21), but none flew often enough under OO 5808 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to OKC only.
One caution: this is a thin sample. 283 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 5808
For a booking, OO 5808 has one of the better records a US domestic flight can show: 85.1% on time and 0.35% cancelled. That is a base rate, not a promise about any single day.
