Carrier by carrier

Which airlines run best out of MCO

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.

The best time of day to leave MCO

The 8pm–5am window is where this operation falls apart: 60.8% on time, against 92.0% 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 8am–11am window is the busiest, with 32,149 flights scheduled in it.

Across the year

When MCO runs late

MCO's year swings by 16 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 68.2% on time, 16 points below September, the best at 84.6%. 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 15,497 flights.

Across the week, Wednesday is the strongest day at 82.1% on time and Sunday the weakest at 67.0%, a spread of 15 points.

MCO month by month

From Europe

Transatlantic routes into MCO

11 European airports send scheduled passenger flights to MCO, 7,208 flights a year in both directions by the DOT's international count. The DOT keeps no delay record for international flights; the UK routes carry the CAA's departure punctuality, and every route sets its departure airport's EUROCONTROL figures beside MCO's own record above.

Delay causes

Why MCO gets delayed

Late-arriving aircraft accounts for 43% of the 2.85 million delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    43%
  • Carrier
    28%
  • National Airspace System
    23%
  • Extreme weather
    5%
  • Security
    0%

43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2.85 million reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 2,852,202 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 92.0% on time here.

Cancellations sit at 1.81% against a national 1.89%, which is ordinary. Diversions add another 0.28%.

9.5% 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.

159,940 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.

What to do with this

Flying out of MCO

Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 84.6% on time and July 68.2%, a swing of 16 points. If the dates move at all, move them out of July before you think about anything else. 156,605 completed flights over 12 months sit behind that.

Common questions

MCO delay questions

How often is Orlando (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 25.4% of the 159,940 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 Orlando (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 Orlando (MCO)?

The 5am–8am departure window is the strongest at 92.0% on time. The 8pm–5am window is the weakest at 60.8%, 31 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 Orlando (MCO)?

July is the weakest month at 68.2% on time, compared with 84.6% in September. Across the year that is 16 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
