B6 2052 earns an F−, which is as low as this site's scale goes for a reason. Only 54.1% of flights arrive inside the 15-minute window, 23 points worse than the national rate of 77.6%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 345 flights, with a median arrival 11 minutes late.

The national on-time rate over the same period is 77.6%, so B6 2052 runs 23 points behind the country as a whole. Across a thousand flights that is about 235 extra late arrivals.

These figures cover 345 flights between July 2025 and June 2026. Beyond the headline rate, 22.2% 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 2052 flies

B6 2052 flies MCO to BOS without a single fixed slot. Its most common scheduled departure was 15:55, used on 61 of 345 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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

A 15:55 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and B6 2052 runs 18 points worse at 54.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

B6 2052 quarter by quarter

B6 2052 did not run the same all year. Its best quarter was Oct–Dec 2025 at 58.1% on time and its weakest Jul–Sep 2025 at 44.8%, a swing of 13 points on roughly 86 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.

Jul–Sep 202592 flights44.8%
Oct–Dec 202590 flights58.1%
Jan–Mar 202690 flights56.6%
Apr–Jun 202673 flights57.5%

Scale runs 35% to 65%. Rows with fewer than 30 flights show a dash.

By weekday, B6 2052 did best on Wednesday at 63.6% on time and worst on Sunday at 41.3%. Each day rests on about 49 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 2052 runs late

One category carries most of the weight here. National Airspace System accounts for 50% of the 12,000 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
27%
Carrier

Extreme weather
3%

50% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 6,171 minutes out of 12,000, against a national NAS share of 21%. The split is drawn from 12,308 delay minutes reported on B6 2052.

Cancellations run at 4.35%, against 1.81% nationally. That is roughly one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

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. 22.2% 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 1,121 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 345 flights under B6 2052 in the data flew MCO to BOS. 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. 345 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 2052

For a booking, the cancellation rate is the figure to plan around on B6 2052: 4.35% of its 345 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
