These figures cover 305 flights between July 2025 and June 2026. Beyond the headline rate, 19.0% 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 1053 flies
B6 1053 flies JFK to PBI without a single fixed slot. Its most common scheduled departure was 18:50, used on 65 of 305 flights, with 18:55 (41 flights) and 08:45 (34 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 18:50 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and B6 1053 runs 8 points worse at 60.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
B6 1053 quarter by quarter
B6 1053 did not run the same all year. Its best quarter was Apr–Jun 2026 at 72.6% on time and its weakest Jul–Sep 2025 at 43.2%, a swing of 29 points on roughly 76 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 flights43.2%
- Oct–Dec 202550 flights66.7%
- Jan–Mar 202676 flights62.9%
- Apr–Jun 202687 flights72.6%
Scale runs 35% to 80%. Rows with fewer than 30 flights show a dash.
By weekday, B6 1053 did best on Tuesday at 73.8% on time and worst on Sunday at 54.1%. Each day rests on about 44 flights, so a gap of 20 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 1053 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 50% of the 9,449 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
- 32%Carrier
- 18%National Airspace System
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 9,449 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 9,449 delay minutes reported on B6 1053.
Cancellations run at 3.93%, against 1.81% nationally. That is about 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. 19.0% 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 1,028 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 305 flights under B6 1053 in the data flew JFK 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. 305 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 1053
For a booking, the cancellation rate is the figure to plan around on B6 1053: 3.93% of its 305 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
