Route reliability record

MCO→JFK

Orlando to New York

Flights: 4,943
Period: June 2025 to May 2026
Distance: 944 mi
Carriers: 3

This route sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.4%. The late ones land a little over an hour behind schedule. That rests on 4,943 flights, of which Delta Air Lines flew 1,980 at 77.6% on time.

The national on-time rate over the same period is 77.4%, so this route runs 4 points behind the country as a whole. Across a thousand flights that is about 42 extra late arrivals.

These figures cover 4,943 flights between June 2025 and May 2026. Beyond the headline rate, 12.0% 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

Which airline is most reliable on MCO to JFK

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 77.6% of the time; JetBlue Airways manages 68.3%. Sample sizes sit next to every figure, because a two-point gap across 2,639 flights means less than a ten-point one.

On-time performance by carrier on MCO to JFK
Airline	Flights	On time	Avg delay	Cancelled	Grade
Frontier Airlinesthin sample	324	86.6%	61 min	1.23%	A
Delta Air Lines	1,980	77.6%	84 min	3.08%	B−
JetBlue Airways	2,639	68.3%	81 min	3.03%	C−

Delta Air Lines cancels 3.1% 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

The best time of day to leave

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 43 points, against 9 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am1,290 flights91.8%
8am–11am569 flights82.7%
11am–2pm1,089 flights72.2%
2pm–5pm633 flights70.6%
5pm–8pm865 flights55.8%
8pm–5am497 flights49.2%

Scale runs 40% to 95%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 49.2% on time, against 91.8% 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.

Across the year

When delays peak on this route

This route's year swings by 32 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.

Darker means more delays. Figures are on-time percentages.September best, July worst

July is the worst month at 55.2% on time, 32 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.

Across the week, Tuesday is the strongest day at 79.0% on time and Sunday the weakest at 65.3%. 14 points is a smaller lever than departure hour, but it is free.

Delay causes

Why this route gets delayed

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 105,000 reported delay minutes.

Late-arriving aircraft

34%

Security
0%

35% 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 105,000 reported delay minutes here, that single category outweighs weather by 9 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.

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 36,000 minutes out of 105,000, against a national NAS share of 21%.

Cancellations run at 2.93%, against 1.80% 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 actually costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.0% of arrivals land a full hour or more behind schedule, against 8.2% 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 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. 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 72.8% on time across 4,932 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 4,943 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 this route

Put together: the delay figures matter less here than the 2.93% 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.

Common questions

MCO to JFK questions

How often is MCO to JFK delayed?

About one flight in four arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 26.8% of the 4,943 flights in this analysis, against 22.6% nationally. Delayed flights are late by a little over an hour on average.

Which airline is most reliable on MCO to JFK?

Delta Air Lines leads at 77.6% on time across 1,980 flights. JetBlue Airways is at the other end on 68.3%, a gap of 9 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.

What time of day has the fewest delays on MCO to JFK?

The 5am–8am departure window is the strongest at 91.8% on time. The 8pm–5am window is the weakest at 49.2%, 43 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.

How bad are July delays on MCO to JFK?

July is the weakest month at 55.2% on time, compared with 86.9% in September. Across the year that is 32 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.

Where to go next

Direction matters. MCO to JFK and JFK to MCO are scored separately because they are separate operations, with different departure banks and different aircraft. Compare the return leg.
