Share of 324 completed flights by arrival against schedule.
26 of 98 late departures made up the time and arrived on time, 27% of them. In the other direction, 27 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at MCO.
The worst days
Worst days for B6 83
The latest arrival of the period was on 22 June 2026, 8 hours 45 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.

|---|---|---|
| 22 June 2026 | 8 hours 45 minutes | Late-arriving aircraft |

Delay causes
Why B6 83 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 6,967 reported delay minutes.
- 37%Late-arriving aircraft
- 29%Carrier
- 26%National Airspace System
- 7%Extreme weather
- 1%Security
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,967 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 6,967 delay minutes reported on B6 83.
Cancellations run at 2.95%, against 1.89% nationally. That is roughly one flight in 30 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
11.4% 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 339 flights under B6 83 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. 339 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 83
For a booking, the cancellation rate is the figure to plan around on B6 83: 2.95% of its 339 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.
