Route reliability record

MCO→LGA

Orlando to New York

Flights: 5,262
Period: July 2025 to June 2026
Distance: 950 mi
Carriers: 5

This route carries a cancellation problem, not just a delay problem: 3.8% of scheduled flights never operate, against 1.8% nationally. Of the ones that do fly, about seven flights in ten 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 5,262 flights, of which Delta Air Lines flew 2,171 at 76.0% on time.

Delta Air Lines is the most reliable of the four carriers covered here at 76.0% on time across 2,171 flights.

These figures cover 5,262 flights between July 2025 and June 2026. Beyond the headline rate, 14.0% 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 LGA

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.

On-time performance by carrier on MCO to LGA
Airline	Flights	On time	Avg delay	Cancelled	Grade
Delta Air Lines	2,171	76.0%	74 min	4.42%	B−
Frontier Airlinesthin sample	281	71.1%	71 min	2.14%	C
JetBlue Airways	1,205	64.4%	78 min	2.57%	D
Spirit Airlines	695	61.8%	72 min	5.47%	D−
American Airlines	910	59.5%	94 min	3.41%	D−

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

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 40 points, against 17 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am669 flights92.9%
8am–11am688 flights83.9%
11am–2pm1,118 flights66.5%
2pm–5pm1,301 flights65.1%
5pm–8pm1,109 flights53.4%
8pm–5am377 flights55.5%

Scale runs 45% to 100%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 53.4% on time, against 92.9% 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 2pm–5pm window is the busiest, with 1,301 flights scheduled in it.

Across the year

When delays peak on this route

This route's year swings by 29 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, March worst

September is the best month on the calendar at 86.4% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. March was the busiest month here, with 521 flights.

Across the week, Wednesday is the strongest day at 75.1% on time and Sunday the weakest at 56.6%. 18 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 126,000 reported delay minutes.

National Airspace System
42%
Late-arriving aircraft
34%
Carrier
20%
Extreme weather
5%
Security
0%

42% 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 52,000 minutes out of 126,000, against a national NAS share of 21%. The split is drawn from 125,746 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 92.9% on time here.

Cancellations run at 3.84%, against 1.81% nationally. That is about one flight in 25 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. 14.0% 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 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 70.2% on time across 5,262 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 5,262 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 3.84% 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. 5,029 completed flights over 12 months sit behind that.

Common questions

MCO to LGA questions

How often is MCO to LGA delayed?

About one flight in three arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 31.7% of the 5,262 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.

Which airline is most reliable on MCO to LGA?

Delta Air Lines leads at 76.0% on time across 2,171 flights. American Airlines is at the other end on 59.5%, a gap of 17 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 LGA?

The 5am–8am departure window is the strongest at 92.9% on time. The 5pm–8pm window is the weakest at 53.4%, 40 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 March delays on MCO to LGA?

March is the weakest month at 57.7% on time, compared with 86.4% in September. Across the year that is 29 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 LGA and LGA to MCO are scored separately because they are separate operations, with different departure banks and different aircraft. Compare the return leg.
