These figures cover 299 flights between September 2025 and August 2026. The median arrival is 6 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.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 December 2025 | 5 hours 29 minutes | National Airspace System |
| 10 November 2025 | 4 hours 37 minutes | National Airspace System |

Delay causes
Why OO 5364 runs late
Carrier accounts for 47% of the 3,007 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Carrier
- 34%National Airspace System
- 11%Extreme weather
- 8%Late-arriving aircraft
34% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,018 minutes out of 3,007, against a national NAS share of 21%. The split is drawn from 3,007 delay minutes reported on OO 5364.
Cancellations sit at 2.01% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
5.1% 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 an hour and a half, which a normal layover absorbs.
The 693 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 three other city pairs in the data, including ORD to CRW (15), CHA to ORD (14) and CID to ORD (6), but none flew often enough under OO 5364 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to OKC to ORD only.
One caution: this is a thin sample. 299 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 5364
