Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on MCO to LGA draws a D. 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 1,205 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 2,171 at 76.0% on time.
Delta Air Lines is the most reliable of the three carriers covered here at 76.0% on time across 2,171 flights.

These figures cover 1,205 flights between July 2025 and June 2026. Beyond the headline rate, 16.3% 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 MCO to LGA
JetBlue flew 1,205 of the 5,262 flights on MCO to LGA, about 23% of it. Its 64.4% on time is 4 points worse than the route as a whole, which runs 68.3%. Ranked by on-time rate it is number three of five carriers on the route, where the range runs from Delta at 76.0% to American at 59.5%. One 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 76.0% of the time; American Airlines manages 59.5%. Sample sizes sit next to every figure, because a two-point gap across 910 flights means less than a ten-point one.

Spirit Airlines cancels 5.5% 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 43 points, against 17 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am141 flights90.7%
- 8am–11am144 flights80.9%
- 11am–2pm351 flights63.9%
- 2pm–5pm212 flights64.2%
- 5pm–8pm357 flights47.5%
- 8pm–5am—
Scale runs 40% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 47.5% on time, against 90.7% 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 5pm–8pm window is the busiest, with 357 flights scheduled in it.
Across the year
JetBlue on MCO to LGA through the year
June is the worst month at 49.1% on time, 38 points below September, the best at 86.9%. 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. July was the busiest month here, with 124 flights.
Across the week, Saturday is the strongest day at 69.9% on time and Sunday the weakest at 51.8%. 18 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 50% of the 32,000 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.
- 50%National Airspace System
- 30%Late-arriving aircraft
- 17%Carrier
- 4%Extreme weather
50% 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 16,000 minutes out of 32,000, against a national NAS share of 21%. The split is drawn from 32,338 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 90.7% on time here.
Cancellations run at 2.57%, against 1.81% nationally. That is about one flight in 40 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. 16.3% 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 950 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 66.1% on time across 1,207 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.
The sample behind these figures is 1,205 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 LGA
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 86.9% on time and June 49.1%, a swing of 38 points. If the dates move at all, move them out of June before you think about anything else. 1,167 completed flights over 12 months sit behind that.
