These figures cover 306 flights between July 2025 and June 2026. Beyond the headline rate, 13.2% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When OO 4980 flies
OO 4980 flies PVU to DFW without a single fixed slot. Its most common scheduled departure was 13:54, used on 55 of 306 flights, with 15:57 (37 flights) and 13:55 (32 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 13:54 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 4980 runs 3 points worse at 75.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
OO 4980 quarter by quarter
OO 4980 did not run the same all year. Its best quarter was Oct–Dec 2025 at 79.5% on time and its weakest Jul–Sep 2025 at 68.2%, a swing of 11 points on roughly 77 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.
- Jul–Sep 202592 flights68.2%
- Oct–Dec 202589 flights79.5%
- Jan–Mar 202690 flights79.1%

By weekday, OO 4980 did best on Wednesday at 90.7% on time and worst on Sunday at 63.0%. Each day rests on about 44 flights, so a gap of 28 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 4980 runs late
One category carries most of the weight here. Carrier accounts for 67% of the 6,939 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.
- 67%Carrier
- 16%Extreme weather
- 12%Late-arriving aircraft
- 5%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 2.6 times the usual weather exposure. The split is drawn from 6,939 delay minutes reported on OO 4980.
Cancellations sit at 2.29% against a national 1.81%, which is ordinary. Diversions add another 0.98%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.2% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 958 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 three other city pairs in the data, including BUR to PHX (37), PHX to BUR (37) and DFW to PVU (29), but none flew often enough under OO 4980 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PVU to DFW only.
One caution: this is a thin sample. 306 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 4980
For a booking, OO 4980 is a flight to put a long connection behind. 13.2% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
