These figures cover 352 flights between September 2025 and August 2026. The median arrival is 13 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 |
|---|---|---|
| 17 January 2026 | 17 hours 6 minutes | Late-arriving aircraft |
| 21 February 2026 | 12 hours 34 minutes | Carrier |
| 18 January 2026 | 9 hours 29 minutes | Carrier |

Delay causes
Why OO 5678 runs late
Carrier accounts for 48% of the 8,965 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Carrier
- 32%Late-arriving aircraft
- 16%Extreme weather
- 4%National Airspace System
Extreme weather accounts for 16% 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 2.7 times the usual weather exposure. The split is drawn from 8,965 delay minutes reported on OO 5678.
Cancellations sit at 1.42% against a national 1.89%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
6.9% 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 2.9 hours, which a normal layover absorbs.
The 604 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 ORD to CVG (2), but none flew often enough under OO 5678 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MOT to DEN only.
One caution: this is a thin sample. 352 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 5678
For a booking, OO 5678 has one of the better records a US domestic flight can show: 85.3% on time and 1.42% cancelled. That is a base rate, not a promise about any single day.
