These figures cover 364 flights between September 2025 and August 2026. The median arrival is 8 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.

Delay causes
Why OO 5333 runs late
Carrier accounts for 51% of the 3,493 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Carrier
- 42%Late-arriving aircraft
- 4%Extreme weather
- 2%National Airspace System
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,493 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 3,493 delay minutes reported on OO 5333.
Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 0.27%.
Connections and routes
What a delay on this flight costs
5.8% 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 about an hour, which a normal layover absorbs.
The 563 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 MEM to ORD (1), but none flew often enough under OO 5333 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to MAF only.
One caution: this is a thin sample. 364 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 5333
For a booking, OO 5333 has one of the better records a US domestic flight can show: 85.0% on time and 1.10% cancelled. That is a base rate, not a promise about any single day.
