JetBlue on MCO to JFK carries a cancellation problem, not just a delay problem: 4.3% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about seven flights in ten arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 2,600 flights, with a median arrival 3 minutes early.

The national on-time rate over the same period is 77.3%, so JetBlue on MCO to JFK runs 6 points behind the country as a whole. Across a thousand flights that is about 58 extra late arrivals.

Carrier by carrier

JetBlue against every carrier on MCO to JFK

JetBlue flew 2,600 of the 4,813 flights on MCO to JFK, most of the route. Its 71.5% on time is 3 points worse than the route as a whole, which runs 74.9%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Frontier at 87.3% to JetBlue at 71.5%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

When JetBlue runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 40 points, against half a point between the best and worst carrier.

5am–8am591 flights89.3%
8am–11am433 flights82.5%
11am–2pm542 flights71.5%
2pm–5pm361 flights59.3%
5pm–8pm472 flights56.9%
8pm–5am201 flights49.5%

Scale runs 40% to 95%.

The 8pm–5am window is where this operation falls apart: 49.5% on time, against 89.3% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 591 flights scheduled in it.

Across the year

JetBlue on MCO to JFK through the year

Darker means more delays. Figures are on-time percentages.May best, December worst

December is the weak month at 58.1% on time, against 83.2% in May. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. April was the busiest month here, with 276 flights.

Across the week, Tuesday is the strongest day at 77.3% on time and Sunday the weakest at 63.2%, a spread of 14 points.

Arrival by arrival

How late JetBlue on MCO to JFK runs when it is late

Share of 2,483 completed flights by arrival against schedule.

99 of 664 late departures made up the time and arrived on time, 15% of them. In the other direction, 143 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 JFK.

The latest arrival of the period was on 16 March 2026, 17 hours 55 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across March, December and August, with no single month standing out.

Delay causes

Why JetBlue runs late on this route

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 60,000 reported delay minutes.

Late-arriving aircraft
40%
National Airspace System
34%
Carrier
21%
Extreme weather
5%
Security
0%

40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 60,000 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 60,160 reported delay minutes.

34% 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 20,000 minutes out of 60,000, against a national NAS share of 21%.

Cancellations run at 4.31%, against 1.89% 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 stage length

What a delay here costs

13.5% 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.

The return leg runs 71.6% on time across 2,592 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

The sample behind these figures is 2,600 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this

Booking JetBlue on MCO to JFK

Put together: the delay figures matter less here than the 4.31% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 2,483 completed flights over 12 months sit behind that.
