F9 4602 earns a D, which is as low as this site's scale goes for a reason. Only 56.0% of flights arrive inside the 15-minute window, 22 points worse than the national rate of 77.6%. Late arrivals average an hour and a half. Treat any tight connection here as a coin flip. That rests on 360 flights, with a median arrival 6 minutes late.
The national on-time rate over the same period is 77.6%, so F9 4602 runs 22 points behind the country as a whole. Across a thousand flights that is about 216 extra late arrivals.

These figures cover 360 flights between July 2025 and June 2026. Beyond the headline rate, 22.4% 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 4602 flies
F9 4602 flies ATL to EWR without a single fixed slot. Its most common scheduled departure was 22:40, used on 115 of 360 flights, with 22:45 (64 flights) and 22:15 (49 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 22:40 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and F9 4602 runs 15 points worse at 56.0%. 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 4602 quarter by quarter
F9 4602 did not run the same all year. Its best quarter was Apr–Jun 2026 at 61.1% on time and its weakest Jul–Sep 2025 at 44.4%, a swing of 17 points on roughly 90 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 4602 did best on Wednesday at 71.4% on time and worst on Sunday at 39.6%. Each day rests on about 51 flights, so a gap of 32 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 4602 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 55% of the 13,000 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.
- 55%Late-arriving aircraft
- 30%Carrier
- 14%National Airspace System
- 1%Extreme weather
55% 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 13,000 reported delay minutes here, that single category outweighs weather by 50 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 13,091 delay minutes reported on F9 4602.
Cancellations sit at 1.94% against a national 1.81%, which is ordinary. Diversions add another 0.28%.
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. 22.4% 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.
The 746 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 360 flights under F9 4602 in the data flew ATL to EWR. 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. 360 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 4602
For a booking, F9 4602 is a flight to put a long connection behind. 22.4% 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.
