Share of 272 completed flights by arrival against schedule.

A late pushback is often recovered here: of 42 departures that left 15 minutes late or more, 13 still arrived on time. In the other direction, 47 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ATL.

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 5,551 reported delay minutes.

National Airspace System
41%
Carrier
36%
Late-arriving aircraft
13%
Extreme weather
11%

41% 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 2,254 minutes out of 5,551, against a national NAS share of 21%. The split is drawn from 5,551 delay minutes reported on F9 2409.

Cancellations run at 3.20%, against 1.89% nationally. That is about 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

8.8% of arrivals land an hour or more late, close to the national 8.3%, so 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 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.

Every one of the 281 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. 281 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: 3.20% of its 281 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.
