Delay causes
Why YX 4658 runs late
Late-arriving aircraft accounts for 46% of the 4,185 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 34%National Airspace System
- 18%Carrier
- 2%Extreme weather
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,185 reported delay minutes here, that single category outweighs weather by 19 to one. The split is drawn from 4,185 delay minutes reported on YX 4658.
Cancellations run at 5.53%, against 1.89% nationally. That is roughly one flight in twenty 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
9.3% 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 LGA to STL (38), BOS to DCA (18) and MCI to MIA (4), but none flew often enough under YX 4658 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to RDU only.
One caution: this is a thin sample. 253 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 4658
For a booking, the cancellation rate is the figure to plan around on YX 4658: 5.53% of its 253 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
