These figures cover 365 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

11 of 39 late departures made up the time and arrived on time, 28% of them. In the other direction, 40 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at BFL.
The worst days
Worst days for OO 4668
The latest arrival of the period was on 6 March 2026, 4 hours 45 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across March, December, February and July, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 March 2026 | 4 hours 45 minutes | Extreme weather |
| 29 December 2025 | 3 hours 15 minutes | Carrier |
| 24 February 2026 | 2 hours 54 minutes | Extreme weather |
| 17 February 2026 | 2 hours 29 minutes | National Airspace System |
| 16 July 2026 | 2 hours 7 minutes | Late-arriving aircraft |
Delay causes
Why OO 4668 runs late
Carrier accounts for 45% of the 3,196 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 23%Late-arriving aircraft
- 18%Extreme weather
- 14%National Airspace System
Extreme weather accounts for 18% 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 3.0 times the usual weather exposure. The split is drawn from 3,196 delay minutes reported on OO 4668.
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
Badly late arrivals are rare here: only 4.4% land an hour or more behind schedule, against 8.3% 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 845 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.
Every one of the 365 flights under OO 4668 in the data flew DEN to BFL. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 365 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 4668
