These figures cover 312 flights between September 2025 and August 2026. The median arrival is 16 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 |
|---|---|---|
| 29 July 2026 | 10 hours 19 minutes | Carrier |
| 19 March 2026 | 6 hours 48 minutes | Late-arriving aircraft |

Delay causes
Why OO 5787 runs late
Carrier accounts for 69% of the 3,366 delay minutes carriers reported here, and the remaining four split what is left.
- 69%Carrier
- 17%Late-arriving aircraft
- 10%Extreme weather
- 4%National Airspace System
The largest share of delay minutes, 69%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,324 of the 3,366 delay minutes reported here. The split is drawn from 3,366 delay minutes reported on OO 5787.
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
5.4% 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 close to two hours, which a normal layover absorbs.
The 844 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 DEN to JAC (52), but none flew often enough under OO 5787 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to FAT to DEN only.
One caution: this is a thin sample. 312 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 5787
For a booking, OO 5787 has one of the better records a US domestic flight can show: 91.3% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
