Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with JetBlue Airways.

JetBlue on BOS to MCO carries a cancellation problem, not just a delay problem: 3.6% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about two flights in three 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 2,520 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 1,257 at 75.5% on time.

The national on-time rate over the same period is 77.3%, so JetBlue on BOS to MCO runs 11 points behind the country as a whole. Across a thousand flights that is about 107 extra late arrivals.

Carrier by carrier

JetBlue against every carrier on BOS to MCO

JetBlue flew 2,520 of the 4,605 flights on BOS to MCO, most of the route. Its 66.6% on time is 3 points worse than the route as a whole, which runs 69.5%. Ranked by on-time rate it is number four of six carriers on the route, where the range runs from American at 80.7% 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 75.5% of the time; Spirit Airlines manages 58.5%. Sample sizes sit next to every figure, because a two-point gap across 389 flights means less than a ten-point one.

138 of 752 late departures made up the time and arrived on time, 18% of them. In the other direction, 191 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 MCO.

The worst days

Worst days for JetBlue on BOS to MCO

The latest arrival of the period was on 25 February 2026, 8 hours 26 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.

Delay causes

Why JetBlue runs late on this route

Late-arriving aircraft accounts for 46% of the 59,000 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    46%
  • Carrier
    26%
  • National Airspace System
    25%
  • Extreme weather
    2%
  • Security
    0%

46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 59,000 reported delay minutes here, that single category outweighs weather by 20 to one. The split is drawn from 59,487 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 81.7% on time here.

Cancellations run at 3.61%, against 1.89% nationally. That is about 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

13.6% 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 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.

The return leg runs 67.4% on time across 2,527 flights, within about 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 2,520 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 3.61% 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. 2,411 completed flights over 12 months sit behind that.
