Why MCO → MIA flights are cancelled

July 2023 – July 2026

MCO → MIA cancelled 162 of 11,750 scheduled flights — about 1 in every 73. The reason filed most often was extreme weather, 71.6% of the cancellations coded on this route — about 1 in every 101 scheduled flights.

What each reason means

Extreme weather1 in 101

Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.

116 cancellations, 71.6% of the total.

The air traffic system1 in 490

Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.

24 cancellations, 14.8% of the total.

The airline1 in 534

Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.

22 cancellations, 13.6% of the total.

Security—

A terminal evacuation, a security breach, screening equipment failure, or screening queues over 29 minutes.

0 cancellations, 0.0% of the total.

Reason codes are the operating airline’s own filing with US DOT, not an independent finding of fault. Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.

162 coded cancellations were recorded on MCO → MIA; the section appears from 50.

MCO → MIA has an average that understates its risk: a typical arrival is 6 min early, but the worst tenth are 65 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Percentiles over 11,750 operations; cancelled and diverted flights are counted separately.

Will your connection be tight enough?

Layovers at MIA after arriving from MCO.

Connection buffer and chance of missing by layover length, MCO → MIA arrivals
Connection time	Chance of missing	Reads as

60 min	16%	High risk
90 min	9.7%	Some risk
120 min	6.7%	Some risk

This is one leg of a connection. Gate changes and the next flight's own schedule matter too. And a connection can fail before delay is even the question — this route cancels 1.38% of the time and diverts 0.12% of the time, which a late arrival never shows up in.

Chance of missing is the share of 11,574 arrivals on this route that landed later than the connection time less 30 minutes to reach the next gate.

The worst tenth of arrivals on this route land at least 59 minutes late (90th-percentile gate arrival delay), over 11,750 operations.

Share of the delay minutes US DOT attributed to each cause for MCO → MIA. Only delays of 15 minutes or more are attributed.

Late-arriving aircraft is the largest cause on MCO → MIA, at 51.5%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 91.4% of the time and 6–9 PM departures 58.2%.
