These figures cover 363 flights between July 2025 and June 2026. Beyond the headline rate, 8.2% 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 4601 flies
F9 4601 flies EWR to ATL without a single fixed slot. Its most common scheduled departure was 05:59, used on 124 of 363 flights, with 05:55 (97 flights) and 06:00 (74 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 05:59 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 4601 runs 19 points worse at 70.5%. 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 4601 quarter by quarter
F9 4601 did not run the same all year. Its best quarter was Apr–Jun 2026 at 77.8% on time and its weakest Jul–Sep 2025 at 64.4%, a swing of 13 points on roughly 91 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 202591 flights68.6%
- Jan–Mar 202690 flights70.9%
- Apr–Jun 202690 flights77.8%
Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, F9 4601 did best on Tuesday at 86.0% on time and worst on Sunday at 50.0%. Each day rests on about 52 flights, so a gap of 36 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 4601 runs late
One category carries most of the weight here. Carrier accounts for 43% of the 7,263 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.
- 43%Carrier
- 41%National Airspace System
- 13%Late-arriving aircraft
- 4%Extreme weather
The largest share of delay minutes, 43%, 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 3,118 of the 7,263 delay minutes reported here. The split is drawn from 7,263 delay minutes reported on F9 4601.
Cancellations sit at 2.48% against a national 1.81%, which is ordinary. Diversions add another 0.55%.
Connections and routes
What a delay on this flight costs
8.2% 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 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.
The same number turns up on one other city pair in the data, including TYS to ATL (1), but none flew often enough under F9 4601 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to ATL only.
One caution: this is a thin sample. 363 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.
