Delay causes
Why YX 4792 runs late
Late-arriving aircraft accounts for 70% of the 6,838 delay minutes carriers reported here, and the remaining four split what is left.
- 70%Late-arriving aircraft
- 16%National Airspace System
- 12%Carrier
- 2%Extreme weather
- 0%Security
70% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,838 reported delay minutes here, that single category outweighs weather by 46 to one. The split is drawn from 6,838 delay minutes reported on YX 4792.
Cancellations run at 10.51%, against 1.89% nationally. That is about 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
16.7% 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 500 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 314 flights under YX 4792 in the data flew LGA to ILM. 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. 314 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 4792
For a booking, the cancellation rate is the figure to plan around on YX 4792: 10.51% of its 314 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.
