These figures cover 265 flights between September 2025 and August 2026. The median arrival is 7 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.

Share of 261 completed flights by arrival against schedule.

8 of 45 late departures made up the time and arrived on time, 18% of them. In the other direction, 17 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 RAP.

Delay causes

Why OO 5265 runs late

Carrier accounts for 43% of the 4,484 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
43%
Late-arriving aircraft
27%
National Airspace System
19%
Extreme weather
12%

Extreme weather accounts for 12% 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 1.9 times the usual weather exposure. The split is drawn from 4,484 delay minutes reported on OO 5265.

Cancellations sit at 1.13% against a national 1.89%, which is ordinary. Diversions add another 0.38%.

Connections and routes

What a delay on this flight costs

7.7% 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 an hour and a half, which a normal layover absorbs.

The same number turns up on four other city pairs in the data, including CLE to ORD (46), ORD to ATW (32) and SFO to SLC (1), but none flew often enough under OO 5265 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to RAP only.

One caution: this is a thin sample. 265 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 5265

For a booking, read OO 5265 as 79.3% on time with 1.13% cancelled over 265 flights. Those are rates from the past twelve months, not a forecast for any particular day.
