F9 1384 flies CLT to PHL without a single fixed slot. Its most common scheduled departure was 15:49, used on 45 of 273 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Delay causes
Why F9 1384 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 57% of the 8,424 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.
- 57%Late-arriving aircraft
- 20%Carrier
- 14%National Airspace System
- 9%Extreme weather
57% 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 8,424 reported delay minutes here, that single category outweighs weather by 6 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 8,424 delay minutes reported on F9 1384.
Cancellations sit at 2.20% against a national 1.81%, which is ordinary. Diversions add another 0.37%.
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. 17.3% 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.
Every one of the 273 flights under F9 1384 in the data flew CLT to PHL. 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. 273 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 1384
For a booking, F9 1384 is a flight to put a long connection behind. 17.3% 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.
