These figures cover 340 flights between July 2025 and June 2026. Beyond the headline rate, 12.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When B6 83 flies
B6 83 flies JFK to MCO without a single fixed slot. Its most common scheduled departure was 12:00, used on 129 of 340 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 12:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and B6 83 runs 11 points worse at 67.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
B6 83 quarter by quarter
B6 83 did not run the same all year. Its best quarter was Apr–Jun 2026 at 81.6% on time and its weakest Oct–Dec 2025 at 59.1%, a swing of 22 points on roughly 85 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, B6 83 did best on Wednesday at 80.9% on time and worst on Sunday at 47.8%. Each day rests on about 49 flights, so a gap of 33 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 83 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 7,881 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

- 27%National Airspace System
- 23%Carrier
- 1%Security
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 7,881 reported delay minutes here, that single category outweighs weather by 49 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 7,881 delay minutes reported on B6 83.
Cancellations sit at 2.35% against a national 1.81%, which is ordinary. Diversions add another 1.18%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.5% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
Every one of the 340 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. 340 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, B6 83 is a flight to put a long connection behind. 12.5% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
