Delay causes
Why YX 4765 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 5,474 reported delay minutes.
- 40%Late-arriving aircraft
- 38%National Airspace System
- 11%Carrier
- 11%Extreme weather
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,474 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 5,474 delay minutes reported on YX 4765.
Cancellations run at 3.45%, 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
10.4% 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.
The same number turns up on four other city pairs in the data, including DCA to TPA (26), TPA to DCA (26) and ORD to SDF (4), but none flew often enough under YX 4765 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RDU to JFK only.
One caution: this is a thin sample. 290 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 YX 4765
For a booking, the cancellation rate is the figure to plan around on YX 4765: 3.45% of its 290 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.
