These figures cover 356 flights between July 2025 and June 2026. Beyond the headline rate, 9.7% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When B6 1133 flies

B6 1133 flies MCO to SJU without a single fixed slot. Its most common scheduled departure was 15:00, used on 58 of 356 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 15:00 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and B6 1133 runs level with that at 72.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

B6 1133 quarter by quarter

B6 1133 did not run the same all year. Its best quarter was Apr–Jun 2026 at 83.7% on time and its weakest Jul–Sep 2025 at 61.5%, a swing of 22 points on roughly 89 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, B6 1133 did best on Tuesday at 79.6% on time and worst on Saturday at 60.8%. Each day rests on about 51 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 1133 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 7,344 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Late-arriving aircraft
47%
Carrier
32%
National Airspace System
14%
Extreme weather
7%

47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 7,344 reported delay minutes here, that single category outweighs weather by 7 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 7,344 delay minutes reported on B6 1133.

Cancellations sit at 1.12% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.7% of arrivals land a full hour or more behind schedule, against 8.1% 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.

The 1,188 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 356 flights under B6 1133 in the data flew MCO to SJU. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 356 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking B6 1133
