These figures cover 323 flights between September 2025 and August 2026. The median arrival is 10 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 5270 runs late
Late-arriving aircraft accounts for 54% of the 4,261 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 38%Carrier
- 5%National Airspace System
- 3%Extreme weather
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,261 reported delay minutes here, that single category outweighs weather by 17 to one. The split is drawn from 4,261 delay minutes reported on OO 5270.
Cancellations are rare at 0.62%, 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
6.3% 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 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 four other city pairs in the data, including IAH to LIT (29), ABQ to DEN (4) and DEN to OMA (3), but none flew often enough under OO 5270 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. 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 5270
For a booking, OO 5270 has one of the better records a US domestic flight can show: 85.6% on time and 0.62% cancelled. That is a base rate, not a promise about any single day.
