These figures cover 259 flights between July 2025 and June 2026. The median arrival is 3 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 4732 flies
F9 4732 flies ATL to JFK without a single fixed slot. Its most common scheduled departure was 09:37, used on 90 of 259 flights, with 09:15 (35 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 09:3790 flights34.7%
- Departs 09:1535 flights13.5%
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 09:37 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and F9 4732 runs 11 points worse at 73.3%. 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 4732 quarter by quarter
F9 4732 did not run the same all year. Its best quarter was Jul–Sep 2025 at 81.4% on time and its weakest Oct–Dec 2025 at 59.1%, a swing of 22 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 202543 flights81.4%
- Oct–Dec 202545 flights59.1%
- Jan–Mar 202680 flights70.5%
- Apr–Jun 202691 flights78.9%
Scale runs 50% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, F9 4732 did best on Wednesday at 91.4% on time and worst on Sunday at 64.9%. Each day rests on about 37 flights, so a gap of 27 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 4732 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 5,055 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.
- 49%Late-arriving aircraft
- 29%Carrier
- 19%National Airspace System
- 3%Extreme weather
49% 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 5,055 reported delay minutes here, that single category outweighs weather by 17 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 5,055 delay minutes reported on F9 4732.
Cancellations sit at 1.54% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
7.1% 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 760 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 259 flights under F9 4732 in the data flew ATL 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. 259 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 4732
