These figures cover 278 flights between July 2025 and June 2026. Beyond the headline rate, 8.8% 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 1241 flies
B6 1241 flies BDL to PBI without a single fixed slot. Its most common scheduled departure was 08:45, used on 38 of 278 flights, with 07:30 (32 flights) next. 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 08:45 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and B6 1241 runs 4 points worse at 80.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
B6 1241 quarter by quarter
B6 1241 did not run the same all year. Its best quarter was Apr–Jun 2026 at 89.7% on time and its weakest Jan–Mar 2026 at 59.7%, a swing of 30 points on roughly 70 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 1241 did best on Wednesday at 87.9% on time and worst on Sunday at 69.8%. Each day rests on about 40 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 1241 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 50% of the 3,358 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.
- 50%Late-arriving aircraft
- 27%National Airspace System
- 22%Carrier
- 0%Extreme weather
50% 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 3,358 reported delay minutes here, that single category outweighs weather by 50 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 3,358 delay minutes reported on B6 1241.
Cancellations sit at 1.80% against a national 1.81%, which is ordinary. Diversions add another 0.36%.
Connections and routes
What a delay on this flight costs
8.8% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The 1,133 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 278 flights under B6 1241 in the data flew BDL to PBI. 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. 278 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 1241
For a booking, read B6 1241 as 80.5% on time with 1.80% cancelled over 278 flights. Those are rates from the past twelve months, not a forecast for any particular day.
