These figures cover 318 flights between September 2025 and August 2026. The median arrival is 4 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.

Across the year

OO 5884 quarter by quarter

OO 5884 did not run the same all year. Its best quarter was Jul–Sep 2026 at 86.9% on time and its weakest Apr–Jun 2026 at 70.8%, a swing of 16 points on roughly 80 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, OO 5884 did best on Sunday at 86.4% on time and worst on Tuesday at 70.2%. Each day rests on about 45 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

9 of 46 late departures made up the time and arrived on time, 20% of them. In the other direction, 36 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 DEN.

Delay causes

Why OO 5884 runs late

Carrier accounts for 53% of the 5,047 delay minutes carriers reported here, and the remaining four split what is left.

Carrier

National Airspace System
18%
Extreme weather
15%
Late-arriving aircraft
15%

Extreme weather accounts for 15% 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 2.5 times the usual weather exposure. The split is drawn from 5,047 delay minutes reported on OO 5884.

Cancellations are rare at 0.63%, 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

7.6% 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 a little over an hour, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including ICT to IAH (2), but none flew often enough under OO 5884 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RAP to DEN only.

One caution: this is a thin sample. 318 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 5884
