Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on BOS to MCO draws a C. About one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 2,493 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 1,257 at 75.4% on time.
The national on-time rate over the same period is 77.6%, so JetBlue on BOS to MCO runs 10 points behind the country as a whole. Across a thousand flights that is about 97 extra late arrivals.

These figures cover 2,493 flights between July 2025 and June 2026. Beyond the headline rate, 13.0% 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.
Carrier by carrier
JetBlue against every carrier on BOS to MCO
JetBlue flew 2,493 of the 4,606 flights on BOS to MCO, most of the route. Its 67.9% on time is 2 points worse than the route as a whole, which runs 70.1%. Ranked by on-time rate it is number four of six carriers on the route, where the range runs from American at 79.2% to Southwest at 50.0%. Three of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 75.4% of the time; Spirit Airlines manages 63.5%. Sample sizes sit next to every figure, because a two-point gap across 515 flights means less than a ten-point one.

Spirit Airlines cancels 4.1% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

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 30 points, against 12 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am397 flights82.6%
- 8am–11am471 flights77.6%
- 11am–2pm541 flights72.3%
- 2pm–5pm475 flights55.8%
- 5pm–8pm373 flights59.2%
- 8pm–5am236 flights52.4%
Scale runs 45% to 90%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 52.4% on time, against 82.6% 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 11am–2pm window is the busiest, with 541 flights scheduled in it.
Across the year
JetBlue on BOS to MCO through the year
July is the worst month at 58.2% on time, 21 points below September, the best at 79.3%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. April was the busiest month here, with 274 flights.
Across the week, Wednesday is the strongest day at 80.8% on time and Sunday the weakest at 55.1%. 26 points is a smaller lever than departure hour, but it is free.
Delay causes
Why JetBlue runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 56,000 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.

- 28%National Airspace System
- 25%Carrier
- 2%Extreme weather
- 0%Security
45% 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 56,000 reported delay minutes here, that single category outweighs weather by 21 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 56,404 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 82.6% on time here.
Cancellations run at 2.89%, against 1.81% 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 stage length
What a delay here costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.0% 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 1,121 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.
The return leg runs 67.3% on time across 2,495 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 2,493 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 BOS to MCO
Put together: the delay figures matter less here than the 2.89% cancellation rate. A late arrival costs you a little over an hour; 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. 2,399 completed flights over 12 months sit behind that.
