F9 4025 earns a D, which is as low as this site's scale goes for a reason. Only 57.3% of flights arrive inside the 15-minute window, 20 points worse than the national rate of 77.6%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 284 flights, with a median arrival 4 minutes late.

The national on-time rate over the same period is 77.6%, so F9 4025 runs 20 points behind the country as a whole. Across a thousand flights that is about 203 extra late arrivals.

These figures cover 284 flights between July 2025 and June 2026. Beyond the headline rate, 17.6% 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 4025 flies

F9 4025 flies MCO to ATL without a single fixed slot. Its most common scheduled departure was 17:10, used on 51 of 284 flights, with 19:48 (45 flights) and 21:40 (34 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 17:10 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and F9 4025 runs 11 points worse at 57.3%. 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 4025 quarter by quarter

F9 4025 did not run the same all year. Its best quarter was Oct–Dec 2025 at 65.4% on time and its weakest Jul–Sep 2025 at 50.0%, a swing of 15 points on roughly 71 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 202580 flights65.4%
Jan–Mar 202680 flights52.6%

By weekday, F9 4025 did best on Wednesday at 81.6% on time and worst on Sunday at 34.1%. Each day rests on about 41 flights, so a gap of 47 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 4025 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 8,430 reported delay minutes.

Late-arriving aircraft
38%
National Airspace System
31%
Carrier
23%
Extreme weather
8%

38% 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 8,430 reported delay minutes here, that single category outweighs weather by 5 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 8,430 delay minutes reported on F9 4025.

Cancellations sit at 1.76% 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. 17.6% 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.

Every one of the 284 flights under F9 4025 in the data flew MCO to ATL. 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. 284 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 4025

For a booking, F9 4025 is a flight to put a long connection behind. 17.6% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
