These figures cover 281 flights between July 2025 and June 2026. The median arrival is 11 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 4872 flies

F9 4872 flies MCO to JFK without a single fixed slot. Its most common scheduled departure was 07:15, used on 53 of 281 flights, with 07:35 (49 flights) and 07:43 (31 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 07:15 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 4872 runs 3 points worse at 86.6%. 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 4872 quarter by quarter

F9 4872 did not run the same all year. Its best quarter was Oct–Dec 2025 at 92.4% on time and its weakest Jan–Mar 2026 at 78.8%, a swing of 14 points on roughly 94 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 4872 did best on Wednesday at 95.0% on time and worst on Saturday at 78.0%. Each day rests on about 40 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 4872 runs late

One category carries most of the weight here. National Airspace System accounts for 55% of the 2,275 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.

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 800 of the 2,275 delay minutes reported here. The split is drawn from 2,275 delay minutes reported on F9 4872.

Cancellations sit at 1.42% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.9% 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 944 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 281 flights under F9 4872 in the data flew MCO to JFK. 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. 281 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 4872

For a booking, F9 4872 has one of the better records a US domestic flight can show: 86.6% on time and 1.42% cancelled. That is a base rate, not a promise about any single day.
