These figures cover 318 flights between July 2025 and June 2026. Beyond the headline rate, 9.6% 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
When F9 3311 flies
F9 3311 flies MCO to DEN without a single fixed slot. Its most common scheduled departure was 20:59, used on 119 of 318 flights, with 20:42 (35 flights) and 20:33 (35 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 20:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and F9 3311 runs 5 points better at 75.5%. 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 3311 quarter by quarter
F9 3311 did not run the same all year. Its best quarter was Oct–Dec 2025 at 81.6% on time and its weakest Jul–Sep 2025 at 66.7%, a swing of 15 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.
- Jul–Sep 202572 flights66.7%
- Oct–Dec 202589 flights81.6%
- Jan–Mar 202666 flights76.6%
- Apr–Jun 202691 flights75.8%

By weekday, F9 3311 did best on Wednesday at 82.9% on time and worst on Friday at 66.7%. Each day rests on about 45 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 3311 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 63% of the 4,836 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 63%Late-arriving aircraft
- 17%National Airspace System
- 15%Carrier
- 5%Extreme weather
63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,836 reported delay minutes here, that single category outweighs weather by 14 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,836 delay minutes reported on F9 3311.
Cancellations sit at 1.26% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
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. 9.6% 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.
At 1,547 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 318 flights under F9 3311 in the data flew MCO 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. 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
