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 2026 at 35.2%, a swing of 30 points on roughly 77 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 4025 did best on Wednesday at 84.6% on time and worst on Sunday at 34.1%. Each day rests on about 44 flights, so a gap of 50 points is worth noticing but could still narrow in another year.

Share of 299 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 103 departures that left 15 minutes late or more, only 10 made it up before arrival. In the other direction, 41 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ATL.
The worst days
Worst days for F9 4025
The latest arrival of the period was on 17 August 2026, 13 hours 19 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Four of the five worst days fell in August 2026.
| Date | Arrived late by | Largest filed cause |

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 11,000 reported delay minutes.
- 35%National Airspace System
- 33%Late-arriving aircraft
- 23%Carrier
- 9%Extreme weather
35% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 3,900 minutes out of 11,000, against a national NAS share of 21%. The split is drawn from 11,131 delay minutes reported on F9 4025.
Cancellations run at 2.60%, against 1.89% nationally. That is about one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
20.1% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
Every one of the 308 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. 308 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, the cancellation rate is the figure to plan around on F9 4025: 2.60% of its 308 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
