These figures cover 258 flights between July 2025 and June 2026. The median arrival is 10 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 4286 flies

F9 4286 flies DTW to MCO without a single fixed slot. Its most common scheduled departure was 12:44, used on 26 of 258 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 12:44 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and F9 4286 runs level with that at 78.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

F9 4286 quarter by quarter

F9 4286 did not run the same all year. Its best quarter was Apr–Jun 2026 at 89.6% on time and its weakest Jul–Sep 2025 at 69.6%, a swing of 20 points on roughly 65 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 202570 flights69.6%
Oct–Dec 202552 flights78.8%
Jan–Mar 202668 flights76.1%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, F9 4286 did best on Saturday at 89.5% on time and worst on Sunday at 72.1%. Each day rests on about 37 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 4286 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 4,269 reported delay minutes.

Carrier
35%
National Airspace System
33%
Late-arriving aircraft
31%
Extreme weather
1%

The largest share of delay minutes, 35%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,480 of the 4,269 delay minutes reported here. The split is drawn from 4,269 delay minutes reported on F9 4286.

Cancellations sit at 1.16% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

7.5% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 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 258 flights under F9 4286 in the data flew DTW to MCO. 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. 258 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.
