These figures cover 323 flights between September 2025 and August 2026. The median arrival is 4 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.

Arrival by arrival
How late OO 5795 runs when it is late

Share of 322 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 43 departures that left 15 minutes late or more, only 5 made it up before arrival. In the other direction, 31 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 TUL.
The worst days
Worst days for OO 5795
The latest arrival of the period was on 29 November 2025, 6 hours 29 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across November, September, March, December and January, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 29 November 2025 | 6 hours 29 minutes | National Airspace System |
| 13 September 2025 | 5 hours 17 minutes | Extreme weather |
| 7 March 2026 | 4 hours 19 minutes | Carrier |
| 31 December 2025 | 3 hours 45 minutes | Late-arriving aircraft |
| 12 January 2026 | 3 hours 27 minutes | Late-arriving aircraft |
Delay causes
Why OO 5795 runs late
Carrier accounts for 44% of the 4,592 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Carrier
- 24%Late-arriving aircraft
- 22%National Airspace System
- 11%Extreme weather
The largest share of delay minutes, 44%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,029 of the 4,592 delay minutes reported here. The split is drawn from 4,592 delay minutes reported on OO 5795.
Cancellations are rare at 0.31%, 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
6.2% 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 about an hour, which a normal layover absorbs.
The 585 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 one other city pair in the data, including OMA to ORD (20), but none flew often enough under OO 5795 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to TUL only.
One caution: this is a thin sample. 323 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 5795
