| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 January 2026 | 15 hours 20 minutes | Carrier |
| 19 November 2025 | 6 hours 44 minutes | Carrier |
| 26 July 2026 | 4 hours 50 minutes | Late-arriving aircraft |

Delay causes
Why OO 4980 runs late
Carrier accounts for 65% of the 6,267 delay minutes carriers reported here, and the remaining four split what is left.
- 65%Carrier
- 17%Late-arriving aircraft
- 14%Extreme weather
- 5%National Airspace System
Extreme weather accounts for 14% 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 2.3 times the usual weather exposure. The split is drawn from 6,267 delay minutes reported on OO 4980.
Cancellations sit at 2.23% against a national 1.89%, which is ordinary. Diversions add another 0.37%.
Connections and routes
What a delay on this flight costs
13.0% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
The same number turns up on five other city pairs in the data, including DFW to PVU (54), BUR to PHX (37) and PHX to BUR (37), 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. 269 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. 13.0% 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.
