What stands out

This route's worst arrivals run unusually far past its typical one, a bigger gap than 94% of 4,598 comparable routes.

A typical arrival is 3 min early, but the worst tenth run 75 minutes worse than that.

Why BOS → MCO flights are cancelled

July 2023 – July 2026

BOS → MCO cancelled 318 of 14,916 scheduled flights — about 1 in every 47. The reason filed most often was extreme weather, 55.7% of the cancellations coded on this route — about 1 in every 84 scheduled flights.

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

78 cancellations, 24.5% of the total.

The air traffic system1 in 237

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

63 cancellations, 19.8% 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.

BOS → MCO has an average that understates its risk: a typical arrival is 3 min early, but the worst tenth are 75 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 14,916 operations; cancelled and diverted flights are counted separately.

Will your connection be tight enough?

Layovers at MCO after arriving from BOS.

Connection buffer and chance of missing by layover length, BOS → MCO arrivals
Connection time	Chance of missing	Reads as
30 min	44%	Likely to miss
45 min	29%	High risk
60 min	20%	High risk
90 min	12%	Some risk
120 min	7.6%	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 2.13% of the time and diverts 0.56% of the time, which a late arrival never shows up in.

Chance of missing is the share of 14,515 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 72 minutes late (90th-percentile gate arrival delay), over 14,916 operations.

Weather2.6%

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

Late-arriving aircraft is the largest cause on BOS → MCO, at 35.3%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 83.6% of the time and 3–6 PM departures 61.6%.

How this route holds up in bad weather

July 2023 – July 2026

Bad weather raises cancellations by a similar amount at both ends of BOS to MCO: 3.9 times the normal rate at BOS and 3.2 times at MCO. Cancelled in bad weather against normal hours: BOS 5.3% against 1.4%, MCO 4.0% against 1.3%. Flights that did leave MCO in bad weather arrived on time 54.1% of the time, against 76.3% in normal hours.
