Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on MHT to MCO lands a B, about a point worse than the national rate of 77.6%. About one flight in four 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 366 flights, with a median arrival 6 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate JetBlue on MHT to MCO from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on MHT to MCO, 868 flights
These figures cover 366 flights between July 2025 and June 2026. Beyond the headline rate, 10.3% 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 MHT to MCO
JetBlue flew 366 of the 868 flights on MHT to MCO, about 42% of it. Its 76.3% on time is about level with the route as a whole at 77.6%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from Southwest at 78.6% to JetBlue at 76.3%.
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 12 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am205 flights81.5%
- 8am–11am3 flights—
- 11am–2pm—
- 2pm–5pm156 flights69.3%
- 5pm–8pm2 flights—
- 8pm–5am—
Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 81.5% of the time, against 69.3% for the afternoon window. That is 12 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 205 flights scheduled in it.
Across the year
JetBlue on MHT to MCO through the year
July is the worst month at 43.3% on time, 53 points below April, the best at 96.7%. 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. May was the busiest month here, with 32 flights.
Across the week, Wednesday is the strongest day at 82.7% on time and Sunday the weakest at 68.6%. 14 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. National Airspace System accounts for 52% of the 5,864 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.
- 52%National Airspace System
- 33%Late-arriving aircraft
- 13%Carrier
- 2%Extreme weather
52% 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 3,056 minutes out of 5,864, against a national NAS share of 21%. The split is drawn from 5,864 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 81.5% on time here.
Cancellations sit at 1.64% against a national 1.81%, which is ordinary. Diversions add another 0.55%.
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. 10.3% 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 1,142 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 77.8% on time across 366 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 366 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 JetBlue on MHT to MCO
Put together: treat all of this as provisional. 366 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 76.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 358 completed flights over 12 months sit behind that.
