These figures cover 291 flights between July 2025 and June 2026. Beyond the headline rate, 16.3% 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 2144 flies

B6 2144 flies PBI to EWR without a single fixed slot. Its most common scheduled departure was 18:00, used on 53 of 291 flights, with 07:05 (33 flights) and 07:12 (31 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 18:00 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and B6 2144 runs 3 points worse at 65.6%. 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 2144 quarter by quarter

B6 2144 did not run the same all year. Its best quarter was Jul–Sep 2025 at 90.3% on time and its weakest Oct–Dec 2025 at 33.9%, a swing of 56 points on roughly 73 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 2144 did best on Tuesday at 78.0% on time and worst on Sunday at 55.0%. Each day rests on about 42 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 2144 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 7,513 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.

46% 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 7,513 reported delay minutes here, that single category outweighs weather by 46 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 7,513 delay minutes reported on B6 2144.

Cancellations sit at 2.06% against a national 1.81%, which is ordinary. Diversions add another 1.03%.

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. 16.3% 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 1,024 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 291 flights under B6 2144 in the data flew PBI to EWR. 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. 291 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 2144

For a booking, B6 2144 is a flight to put a long connection behind. 16.3% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
