Delay causes
Why YX 4526 runs late
Late-arriving aircraft accounts for 51% of the 7,909 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Late-arriving aircraft
- 30%National Airspace System
- 14%Carrier
- 5%Extreme weather
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,909 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 7,909 delay minutes reported on YX 4526.
Cancellations run at 9.46%, 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
16.9% 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 1,341 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 296 flights under YX 4526 in the data flew LGA to OKC. 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. 296 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 4526
For a booking, the cancellation rate is the figure to plan around on YX 4526: 9.46% of its 296 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.
