These figures cover 308 flights between July 2025 and June 2026. Beyond the headline rate, 9.7% 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 2409 flies

F9 2409 flies CLE to ATL without a single fixed slot. Its most common scheduled departure was 05:30, used on 101 of 308 flights, with 07:10 (31 flights) and 15:46 (31 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 05:30 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 2409 runs 17 points worse at 72.6%. 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 2409 quarter by quarter

F9 2409 did not run the same all year. Its best quarter was Jul–Sep 2025 at 80.0% on time and its weakest Jan–Mar 2026 at 64.0%, a swing of 16 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.

Jul–Sep 202581 flights80.0%
Oct–Dec 202572 flights78.6%
Jan–Mar 202690 flights64.0%
Apr–Jun 202665 flights68.3%

Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, F9 2409 did best on Friday at 77.1% on time and worst on Tuesday at 64.5%. Each day rests on about 44 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 2409 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 5,927 reported delay minutes.

Carrier
39%
National Airspace System
35%
Late-arriving aircraft
17%
Extreme weather
10%

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 2,058 minutes out of 5,927, against a national NAS share of 21%. The split is drawn from 5,927 delay minutes reported on F9 2409.

Cancellations run at 2.92%, against 1.81% nationally. That is roughly one flight in 30 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.7% 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 554 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 308 flights under F9 2409 in the data flew CLE 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 2409

For a booking, the cancellation rate is the figure to plan around on F9 2409: 2.92% of its 308 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
