These figures cover 312 flights between July 2025 and June 2026. The median arrival is 15 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.
Schedule
When OO 5787 flies
OO 5787 flies FAT to DEN without a single fixed slot. Its most common scheduled departure was 09:00, used on 243 of 312 flights, with 08:55 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 5787 runs 8 points better at 92.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
OO 5787 quarter by quarter
OO 5787 did not run the same all year. Its best quarter was Oct–Dec 2025 at 97.4% on time and its weakest Jan–Mar 2026 at 84.4%, a swing of 13 points on roughly 78 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.

- Oct–Dec 202539 flights97.4%
- Jan–Mar 202690 flights84.4%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, OO 5787 ranged from 88.6% on Sunday to 97.8% on Saturday. With about 45 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why OO 5787 runs late
One category carries most of the weight here. Carrier accounts for 65% of the 2,533 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 65%Carrier
- 23%Late-arriving aircraft
- 7%Extreme weather
- 6%National Airspace System
The largest share of delay minutes, 65%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,637 of the 2,533 delay minutes reported here. The split is drawn from 2,533 delay minutes reported on OO 5787.
Cancellations are rare at 0.00%, below the national 1.81% 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
Badly late arrivals are rare here: only 4.8% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
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: 92.0% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
