These figures cover 364 flights between September 2025 and August 2026. The median arrival is 10 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.

The latest arrival of the period was on 1 June 2026, 10 hours 47 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 |
|---|---|---|
| 1 June 2026 | 10 hours 47 minutes | Carrier |
| 29 December 2025 | 9 hours 38 minutes | Carrier |

Delay causes
Why OO 5093 runs late
Carrier accounts for 63% of the 8,201 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Carrier
- 18%Late-arriving aircraft
- 13%Extreme weather
- 6%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 2.1 times the usual weather exposure. The split is drawn from 8,201 delay minutes reported on OO 5093.
Cancellations are rare at 0.55%, 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
6.9% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 3.0 hours, which a normal layover absorbs.
The same number turns up on three other city pairs in the data, including DEN to COD (21), DEN to BFF (10) and DEN to SHR (6), but none flew often enough under OO 5093 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RKS to DEN only.
One caution: this is a thin sample. 364 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 5093
For a booking, OO 5093 has one of the better records a US domestic flight can show: 87.6% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
