JetBlue Airways at Orlando International

Departures: 18,799
Period: September 2025 to August 2026
Routes: 21
Rank here: #8 of 10

JetBlue Airways at Orlando sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.3%. The late ones land a little over an hour behind schedule. That rests on 18,799 flights, of which United Airlines flew 15,054 at 81.5% on time.

Measured against the airport rather than the country, JetBlue Airways runs 3 points behind 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.

Every carrier at MCO, ranked

Route by route

Where JetBlue Airways flies from MCO

JetBlue Airways operates 21 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 35 points, against 14 points between the best and worst carrier.

5am–8am2,855 flights92.1%
8am–11am3,321 flights84.0%
11am–2pm3,958 flights68.6%
2pm–5pm3,066 flights63.7%
5pm–8pm3,533 flights57.1%
8pm–5am2,066 flights62.1%

Scale runs 50% to 100%.

The 5pm–8pm window is where this operation falls apart: 57.1% on time, against 92.1% 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 11am–2pm window is the busiest, with 3,958 flights scheduled in it.

Across the year

Seasonal pattern

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

July is the worst month at 62.1% on time, 23 points below May, the best at 85.0%. 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. December was the busiest month here, with 1,727 flights.

43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 402,000 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 401,592 reported delay minutes.

Cancellations run at 2.72%, against 1.89% nationally. That is roughly 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.

12.4% 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.

18,799 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. May runs 85.0% on time and July 62.1%, a swing of 23 points. If the dates move at all, move them out of July before you think about anything else. 18,217 completed flights over 12 months sit behind that.

Common questions

JetBlue Airways at MCO

How often is JetBlue Airways at MCO delayed?

Roughly one flight in three arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 28.7% of the 18,799 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 JetBlue Airways 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 JetBlue Airways at MCO?

The 5am–8am departure window is the strongest at 92.1% on time. The 5pm–8pm window is the weakest at 57.1%, 35 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 JetBlue Airways at MCO?

July is the weakest month at 62.1% on time, compared with 85.0% in May. Across the year that is 23 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
