B6 2584 lands a B, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 360 flights, with a median arrival 7 minutes early.
Set against the rest of the country, B6 2584's record is 6 points better than the US average of 77.6%. That gap is worth roughly 55 fewer late arrivals for every thousand flights.

These figures cover 360 flights between July 2025 and June 2026. The median arrival is 7 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.
Schedule
When B6 2584 flies
B6 2584 flies MCO to JFK without a single fixed slot. Its most common scheduled departure was 10:09, used on 64 of 360 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 10:09 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and B6 2584 runs level with that at 83.1%. 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 2584 quarter by quarter
B6 2584 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.5% on time and its weakest Jan–Mar 2026 at 74.4%, a swing of 20 points on roughly 90 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 2584 ranged from 80.0% on Sunday to 86.3% on Tuesday. With about 51 flights behind each day, a spread of 6 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why B6 2584 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 3,765 reported delay minutes.
- 39%National Airspace System
- 35%Late-arriving aircraft
- 26%Carrier
- 0%Security
35% 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 3,765 reported delay minutes here, that single category outweighs weather by 35 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 3,765 delay minutes reported on B6 2584.
Cancellations sit at 1.67% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
5.9% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
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 360 flights under B6 2584 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. 360 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 2584
For a booking, read B6 2584 as 83.1% on time with 1.67% cancelled over 360 flights. Those are rates from the past twelve months, not a forecast for any particular day.
