B6 53 sits in the middle of the pack with a C−. About seven flights in ten arrive on time by the DOT's definition, 7 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 256 flights, with a median arrival 2 minutes late.

The national on-time rate over the same period is 77.6%, so B6 53 runs 7 points behind the country as a whole. Across a thousand flights that is about 71 extra late arrivals.

These figures cover 256 flights between July 2025 and June 2026. Beyond the headline rate, 12.7% 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 53 flies

B6 53 flies JFK to PBI without a single fixed slot. Its most common scheduled departure was 15:15, used on 50 of 256 flights, with 11:00 (32 flights) and 11:29 (27 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 15:15 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and B6 53 runs level with that at 70.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

B6 53 quarter by quarter

B6 53 did not run the same all year. Its best quarter was Apr–Jun 2026 at 84.2% on time and its weakest Jul–Sep 2025 at 56.9%, a swing of 27 points on roughly 64 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 202564 flights56.9%
Oct–Dec 202551 flights70.0%
Jan–Mar 202684 flights70.9%
Apr–Jun 202657 flights84.2%

Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, B6 53 did best on Wednesday at 80.6% on time and worst on Thursday at 54.3%. Each day rests on about 37 flights, so a gap of 26 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 53 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,516 reported delay minutes.

Late-arriving aircraft
36%
National Airspace System
33%
Carrier
24%
Extreme weather
7%

36% 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 4,516 reported delay minutes here, that single category outweighs weather by 5 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 4,516 delay minutes reported on B6 53.

Cancellations run at 4.69%, against 1.81% nationally. That is about one flight in twenty 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. 12.7% 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 1,028 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.

The same number turns up on one other city pair in the data, including JFK to TPA (53), but none flew often enough under B6 53 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to PBI only.

One caution: this is a thin sample. 256 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 53

For a booking, the cancellation rate is the figure to plan around on B6 53: 4.69% of its 256 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
