B6 1084 lands a B−, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 320 flights, with a median arrival 6 minutes early.

These figures cover 320 flights between July 2025 and June 2026. Beyond the headline rate, 10.5% 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 1084 flies
B6 1084 flies MCO to JFK without a single fixed slot. Its most common scheduled departure was 07:00, used on 66 of 320 flights, with 13:30 (47 flights) and 13:50 (43 flights) next. 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and B6 1084 runs 11 points worse at 78.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
B6 1084 quarter by quarter
B6 1084 did not run the same all year. Its best quarter was Jan–Mar 2026 at 87.2% on time and its weakest Jul–Sep 2025 at 74.1%, a swing of 13 points on roughly 80 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.

- Oct–Dec 202589 flights75.9%

By weekday, B6 1084 did best on Saturday at 91.1% on time and worst on Sunday at 68.9%. Each day rests on about 46 flights, so a gap of 22 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 1084 runs late
One category carries most of the weight here. National Airspace System accounts for 44% of the 5,435 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.
- 44%National Airspace System
- 32%Late-arriving aircraft
- 19%Carrier
- 5%Extreme weather
44% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,408 minutes out of 5,435, against a national NAS share of 21%. The split is drawn from 5,435 delay minutes reported on B6 1084.
Cancellations run at 4.06%, against 1.81% nationally. That is about one flight in 25 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.5% 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 320 flights under B6 1084 in the data flew MCO to JFK. 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. 320 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 1084
For a booking, the cancellation rate is the figure to plan around on B6 1084: 4.06% of its 320 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.
