Delay causes
Why YX 4611 runs late
Late-arriving aircraft accounts for 50% of the 6,995 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 32%National Airspace System
- 10%Carrier
- 8%Extreme weather
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,995 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 6,995 delay minutes reported on YX 4611.
Cancellations run at 9.23%, against 1.89% nationally. That is roughly one flight in ten 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
12.7% 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 ATL to LGA (38), ORD to LGA (26) and ORD to ALB (10), but none flew often enough under YX 4611 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to PIT only.
One caution: this is a thin sample. 271 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 4611
For a booking, the cancellation rate is the figure to plan around on YX 4611: 9.23% of its 271 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
