Orlando to San Juan

What the Data Says About MCO to SJU

The Orlando to San Juan corridor (MCO → SJU) covers roughly 1,189 miles and is served by 15 carriers, based on Bureau of Transportation Statistics reporting. Across 35,205 flights in the dataset, this route posts a 74.1% on-time rate with an average delay of 69.3 minutes when flights run late. Over the most recent 24 months of BTS data, 12,490 flights were recorded on this pairing — 99 cancelled (0.8%) and 21 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 15 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 35,205 total flights analyzed, the 74.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 69.3-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Oct 2024 posted the best performance on this corridor at 88% on-time, while Aug 2025 came in at 66% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the MCO to SJU route, the combination of a 74.1% on-time rate, 69.3-minute average delay, 0.8% recent cancellation rate, and 15 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
