Route reliability
July 2023 – July 2026
Better than 35% of comparable major US routes (4,598 compared)
Calculated from 19,399 flights. How this is calculated
SJU → MCO arrives on time 77.0% of the time; the return trip, MCO → SJU, arrives on time 73.7% of the time, a 3.3-point gap between the two directions of the same city pair.
SJU → MCO spends 26.1 minutes on the ground on a 1,189-mile trip: 15.1 minutes from pushback to wheels-up at SJU and 11.0 minutes from touchdown to gate at MCO.

Why SJU → MCO flights are cancelled
July 2023 – July 2026
SJU → MCO cancelled 214 of 19,399 scheduled flights — about 1 in every 91. The reason filed most often was extreme weather, 44.9% of the cancellations coded on this route — about 1 in every 202 scheduled flights.
Share of cancellations
Of 214 cancelled departures carrying a reason code.
What each reason means
Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.
96 cancellations, 44.9% of the total.
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
88 cancellations, 41.1% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
30 cancellations, 14.0% of the total.
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.
214 coded cancellations were recorded on SJU → MCO; the section appears from 50.

Will your connection be tight enough?
Layovers at MCO after arriving from SJU.
| Connection time | Chance of missing | Reads as |
|---|---|---|
| 30 min | 39% | Likely to miss |
| 45 min | 22% | High risk |
| 60 min | 15% | Some risk |
| 90 min | 8.7% | Some risk |
| 120 min | 5.6% | 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 1.10% of the time and diverts 0.30% of the time, which a late arrival never shows up in.
Chance of missing is the share of 19,127 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 51 minutes late (90th-percentile gate arrival delay), over 19,399 operations.

Best time to fly
SJU → MCO flights departing 5–9 AM arrived on time 91.0% of the time, against 65.4% for 3–6 PM departures, a gap of 25.6 percentage points.
By day and hour
On-time arrival rate for each weekday and scheduled departure hour, in local time at the departure airport (SJU).
Hour of departure matters more than day of the week: hourly averages sit a typical 10.8 points from the route-wide rate, weekday averages 1.9 points.

Why SJU → MCO runs late
July 2023 – July 2026
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
screening or terminal security incidents
Share of the delay minutes US DOT attributed to each cause for SJU → MCO. Only delays of 15 minutes or more are attributed.
Late-arriving aircraft is the largest cause on SJU → MCO, at 56.2%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 91.0% of the time and 3–6 PM departures 65.4%.
How this route holds up in bad weather
July 2023 – July 2026
The harder-hit end is MCO, where the flight lands. Its figure counts departures from MCO, so it says more about how that airport copes than about this route. Bad weather cancels 3.2 times the normal rate at MCO against barely any change at SJU. Cancelled in bad weather against normal hours: SJU 1.5% 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.
Bad weather and normal hours at the airports
Scheduled departures, July 2023 – July 2026| Departures from | SJU | MCO |
|---|---|---|
| Cancelled in bad weather | 1.5% | 4.0% |
| Cancelled in normal hours | 1.4% | 1.3% |
| Arrived on time, bad weather | 69.5% | 54.1% |
| Arrived on time, normal hours | 76.4% | 76.3% |
| Departures in bad weather | 2,333 | 33,297 |
These are airport figures, not route figures: every scheduled departure from SJU and MCO, to any destination, in hours the weather report called bad.
