Frontier Airlines at Orlando lands a B, about a point worse than the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 19,073 flights, of which United Airlines flew 15,054 at 81.5% on time.
Measured against the airport rather than the country, Frontier Airlines runs 2 points ahead of the 74.6% weighted average across all carriers at MCO. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

Against the competition
Every carrier at MCO, ranked
The choice of carrier is not cosmetic here. United Airlines arrives on time 81.5% of the time; Allegiant Air manages 67.8%. Sample sizes sit next to every figure, because a two-point gap across 407 flights means less than a ten-point one.

Spirit Airlines cancels 4.3% 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.
Route by route
Where Frontier Airlines flies from MCO
Frontier Airlines operates 25 routes out of MCO with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 26 points, against 14 points between the best and worst carrier.
- 5am–8am4,393 flights89.8%
- 8am–11am3,172 flights83.9%
- 11am–2pm2,263 flights75.9%
- 2pm–5pm3,765 flights69.7%
- 5pm–8pm2,398 flights63.8%
- 8pm–5am3,082 flights67.0%
Scale runs 55% to 95%.
The 5pm–8pm window is where this operation falls apart: 63.8% on time, against 89.8% 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. The 5am–8am window is the busiest, with 4,393 flights scheduled in it.
Across the year
Seasonal pattern
July is the worst month at 67.6% on time, 20 points below September, the best at 87.2%. 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. March was the busiest month here, with 2,006 flights.
Delay causes
What holds this operation up
- 45%Late-arriving aircraft
- 26%Carrier
- 22%National Airspace System
- 8%Extreme weather
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 349,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 349,325 reported delay minutes.
Cancellations sit at 1.68% against a national 1.89%, which is ordinary. Diversions add another 0.22%.
9.8% 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.
19,073 flights sit behind these numbers, which is a large enough sample that the headline rate is not moving on noise. Where a sub-group falls below 30 flights the site shows a dash instead of a percentage.
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 87.2% on time and July 67.6%, a swing of 20 points. If the dates move at all, move them out of July before you think about anything else. 18,711 completed flights over 12 months sit behind that.
Common questions
Frontier Airlines at MCO
How often is Frontier Airlines at MCO delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 23.7% of the 19,073 flights in this analysis, against 22.7% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on Frontier Airlines at MCO?
United Airlines leads at 81.5% on time across 15,054 flights. Allegiant Air is at the other end on 67.8%, a gap of 14 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 Frontier Airlines at MCO?
The 5am–8am departure window is the strongest at 89.8% on time. The 5pm–8pm window is the weakest at 63.8%, 26 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 Frontier Airlines at MCO?
July is the weakest month at 67.6% on time, compared with 87.2% in September. Across the year that is 20 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
