These figures cover 358 flights between September 2025 and August 2026. The median arrival is 3 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.

Across the year
OO 4809 quarter by quarter
OO 4809 did not run the same all year. Its best quarter was Jul–Sep 2026 at 80.6% on time and its weakest Oct–Dec 2025 at 69.2%, a swing of 11 points on roughly 90 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, OO 4809 did best on Thursday at 81.6% on time and worst on Saturday at 67.3%. Each day rests on about 51 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Share of 358 completed flights by arrival against schedule.
6 of 50 late departures made up the time and arrived on time, 12% of them. In the other direction, 43 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 ICT.
The worst days
Worst days for OO 4809
The latest arrival of the period was on 29 November 2025, 8 hours 26 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across November, March, July and August, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 29 November 2025 | 8 hours 26 minutes | Extreme weather |
| 6 March 2026 | 7 hours 8 minutes | Carrier |
| 5 July 2026 | 6 hours 17 minutes | National Airspace System |
| 11 August 2026 | 4 hours 23 minutes | Late-arriving aircraft |
| 22 March 2026 | 4 hours 20 minutes | Carrier |
Delay causes
Why OO 4809 runs late
Carrier accounts for 50% of the 6,107 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Carrier
- 21%National Airspace System
- 14%Extreme weather
- 14%Late-arriving aircraft
Extreme weather accounts for 14% 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 2.4 times the usual weather exposure. The split is drawn from 6,107 delay minutes reported on OO 4809.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
7.8% 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 588 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 two other city pairs in the data, including XNA to IAH (1) and IAH to HRL (1), but none flew often enough under OO 4809 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to ICT only.
One caution: this is a thin sample. 358 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
