Delay causes
Why B6 283 runs late
Late-arriving aircraft accounts for 53% of the 9,042 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 23%Carrier
- 17%National Airspace System
- 7%Extreme weather
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,042 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 9,042 delay minutes reported on B6 283.
Cancellations run at 6.61%, against 1.89% nationally. That is about one flight in fifteen 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
21.8% 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 944 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 257 flights under B6 283 in the data flew JFK to MCO. 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. 257 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 B6 283
For a booking, the cancellation rate is the figure to plan around on B6 283: 6.61% of its 257 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
