These figures cover 253 flights between July 2025 and June 2026. Beyond the headline rate, 9.7% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 17:23 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and F9 2225 runs 8 points better at 76.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
F9 2225 quarter by quarter
F9 2225 did not run the same all year. Its best quarter was Apr–Jun 2026 at 92.9% on time and its weakest Jul–Sep 2025 at 53.0%, a swing of 40 points on roughly 63 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.

- Oct–Dec 202563 flights74.6%

By weekday, F9 2225 did best on Sunday at 80.0% on time and worst on Monday at 63.8%. Each day rests on about 36 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 2225 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,288 reported delay minutes.
- 38%Late-arriving aircraft
- 32%National Airspace System
- 22%Extreme weather
- 8%Carrier
Extreme weather accounts for 22% 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 3.5 times the usual weather exposure. The split is drawn from 4,288 delay minutes reported on F9 2225.
Cancellations sit at 1.19% against a national 1.81%, which is ordinary. Diversions add another 0.79%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.7% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 1,436 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
Every one of the 253 flights under F9 2225 in the data flew RDU to DEN. 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. 253 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.
