The worst days
Worst days for OO 5130
The latest arrival of the period was on 26 July 2026, 10 hours 40 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 26 July 2026 | 10 hours 40 minutes | Carrier |
| 27 December 2025 | 9 hours 29 minutes | Carrier |
| 17 October 2025 | 9 hours 8 minutes | Carrier |

Delay causes
Why OO 5130 runs late
Carrier accounts for 70% of the 9,187 delay minutes carriers reported here, and the remaining four split what is left.
- 70%Carrier
- 14%Late-arriving aircraft
- 13%Extreme weather
- 2%National Airspace System
Extreme weather accounts for 13% 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 2.2 times the usual weather exposure. The split is drawn from 9,187 delay minutes reported on OO 5130.
Cancellations are rare at 0.29%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
9.7% 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 same number turns up on two other city pairs in the data, including BFF to DEN (15) and DEN to BFF (15), but none flew often enough under OO 5130 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RIW to DEN only.
One caution: this is a thin sample. 342 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 5130
For a booking, OO 5130 has one of the better records a US domestic flight can show: 85.9% on time and 0.29% cancelled. That is a base rate, not a promise about any single day.
