These figures cover 269 flights between July 2025 and June 2026. The median arrival is 14 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.

Schedule

When F9 3363 flies

F9 3363 flies MCO to DTW without a single fixed slot. Its most common scheduled departure was 06:00, used on 65 of 269 flights, with 09:06 (27 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 3363 runs level with that at 89.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

F9 3363 quarter by quarter

F9 3363 did not run the same all year. Its best quarter was Apr–Jun 2026 at 97.1% on time and its weakest Oct–Dec 2025 at 78.6%, a swing of 19 points on roughly 67 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, F9 3363 did best on Friday at 95.5% on time and worst on Sunday at 82.9%. Each day rests on about 38 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 3363 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 1,584 reported delay minutes.

Carrier
39%
National Airspace System
21%
Extreme weather
21%
Late-arriving aircraft
19%

Extreme weather accounts for 21% 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 3.4 times the usual weather exposure. The split is drawn from 1,584 delay minutes reported on F9 3363.

Cancellations are rare at 0.74%, below the national 1.81% 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

Badly late arrivals are rare here: only 2.6% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The 957 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 269 flights under F9 3363 in the data flew MCO to DTW. 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. 269 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 F9 3363

For a booking, F9 3363 has one of the better records a US domestic flight can show: 89.8% on time and 0.74% cancelled. That is a base rate, not a promise about any single day.
