Historical statistics for August 2025, not live status or a forecast for this year’s August. For today’s conditions at MCO, see live FAA status.

MCO in August draws a C+. About one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 12,746 flights, of which Delta Air Lines flew 1,637 at 73.6% on time.

Delta Air Lines is the most reliable of the seven carriers covered here at 73.6% on time across 1,637 flights.

MCO across all twelve months

These figures cover 12,746 departures from Orlando International in August 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Against the year

August next to MCO's other months

Against MCO's own year, August ran 7 points worse than the twelve-month rate of 74.3%, which makes it number eleven of twelve months, best first. Cancellations were unusually low for MCO in August, at 0.79% against 1.65% across the year. Either side of it, July ran 67.0% on time and September 84.6%, so a trip moved by a few weeks would have landed in a better stretch.

Departure window

The best time of day to leave MCO in August

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 47 points, against 11 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am2,035 flights92.2%
  • 8am–11am2,732 flights82.6%
  • 11am–2pm1,855 flights74.7%
  • 2pm–5pm2,203 flights59.4%
  • 5pm–8pm2,186 flights45.7%
  • 8pm–5am1,735 flights44.8%

Scale runs 35% to 100%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 44.8% on time, against 92.2% 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 2,732 flights scheduled in it.

Across the week, Tuesday is the strongest day at 81.2% on time and Friday the weakest at 58.6%. 23 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at MCO in August

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 73.6% of the time; American Airlines manages 62.1%. Sample sizes sit next to every figure, because a two-point gap across 1,502 flights means less than a ten-point one.

Delta leads American by 11 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes

What held MCO up in August

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 332,000 reported delay minutes.

  • Late-arriving aircraft
    41%
  • National Airspace System
    22%
  • Carrier
    21%
  • Extreme weather
    16%
  • Security
    0%

Extreme weather accounts for 16% 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 comparison with the other months below is the more useful view of the risk. The national share is 7%, so this operation carries roughly 2.3 times the usual weather exposure. The split is drawn from 332,194 reported delay minutes.

Cancellations are rare at 0.79%, below the national 1.08% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 15.1% of arrivals land a full hour or more behind schedule, against 8.2% 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.

What to do with this

Flying from MCO in August

For a August trip through MCO: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 92.2% on time, and with 15.1% of arrivals an hour or more late, a connection here deserves more slack than the same trip in September would.
