These figures cover 341 flights between July 2025 and June 2026. Beyond the headline rate, 14.6% 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 1441 flies
F9 1441 flies ATL to ORD without a single fixed slot. Its most common scheduled departure was 06:35, used on 55 of 341 flights, with 09:02 (48 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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 06:35 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 1441 runs 19 points worse at 70.8%. 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 1441 quarter by quarter
F9 1441 did not run the same all year. Its best quarter was Apr–Jun 2026 at 76.1% on time and its weakest Jan–Mar 2026 at 64.9%, a swing of 11 points on roughly 85 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 1441 did best on Thursday at 86.3% on time and worst on Saturday at 57.4%. Each day rests on about 49 flights, so a gap of 29 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 1441 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 9,254 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.
- 46%Late-arriving aircraft
- 32%Carrier
- 22%National Airspace System
- 0%Extreme weather
46% 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 9,254 reported delay minutes here, that single category outweighs weather by 46 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 9,254 delay minutes reported on F9 1441.
Cancellations sit at 1.47% 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. 14.6% 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.
The 606 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 341 flights under F9 1441 in the data flew ATL to ORD. 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. 341 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 1441
For a booking, F9 1441 is a flight to put a long connection behind. 14.6% 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.
