Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Frontier Airlines.

Frontier on MCO to LGA sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 7 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 281 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 four carriers covered here at 76.0% on time across 2,171 flights.

These figures cover 281 flights between July 2025 and June 2026. Beyond the headline rate, 12.5% 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

Frontier against every carrier on MCO to LGA

Frontier flew 281 of the 5,262 flights on MCO to LGA, about 5% of it. Its 71.1% on time is 3 points better than the route as a whole, which runs 68.3%. Ranked by on-time rate it is number two of five carriers on the route, where the range runs from Delta at 76.0% to American at 59.5%.

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 Frontier runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 14 points, against 17 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am3 flights—
8am–11am114 flights79.1%
11am–2pm133 flights65.6%
2pm–5pm4 flights—
5pm–8pm26 flights—
8pm–5am1 flights—

Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 65.6% on time against 79.1% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 11am–2pm window is the busiest, with 133 flights scheduled in it.

Across the year

Oct–Dec 202555 flights66.7%

Scale runs 60% to 75%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 71.1% on time across 281 flights.

Quarter by quarter Frontier on MCO to LGA held fairly steady: 66.7% in Oct–Dec 2025, 68.9% in Jan–Mar 2026 and 71.1% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Wednesday is the strongest day at 79.6% on time and Monday the weakest at 60.4%. 19 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Frontier runs late on this route

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 5,644 reported delay minutes.

National Airspace System
42%
Late-arriving aircraft
28%
Carrier
19%
Extreme weather
12%

Extreme weather accounts for 12% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 1.9 times the usual weather exposure. The split is drawn from 5,644 reported delay minutes.

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 2,344 minutes out of 5,644, against a national NAS share of 21%.

Cancellations sit at 2.14% against a national 1.81%, which is ordinary. Diversions add another 0.71%.

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. 12.5% 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 is a different operation and performs like one: it runs 60.0% on time across 282 flights, 11 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 11 points of difference.

One caution: this is a thin sample. 281 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 Frontier on MCO to LGA

Put together: treat all of this as provisional. 281 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 71.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 273 completed flights over 12 months sit behind that.
