Delay causes
Why F9 2387 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 4,544 reported delay minutes.
- 37%Late-arriving aircraft
- 35%Carrier
- 24%National Airspace System
- 5%Extreme weather
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,544 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 4,544 delay minutes reported on F9 2387.
Cancellations run at 2.55%, against 1.89% nationally. That is about one flight in 40 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
10.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
Every one of the 275 flights under F9 2387 in the data flew PHL to CLT. 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. 275 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 2387
For a booking, the cancellation rate is the figure to plan around on F9 2387: 2.55% of its 275 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
