These figures cover 342 flights between July 2025 and June 2026. The median arrival is 11 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When B6 854 flies

B6 854 flies PBI to JFK without a single fixed slot. Its most common scheduled departure was 08:15, used on 54 of 342 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 08:15 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and B6 854 runs 6 points better at 90.4%. 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 854 quarter by quarter

B6 854 did not run the same all year. Its best quarter was Jul–Sep 2025 at 95.3% on time and its weakest Jan–Mar 2026 at 83.9%, a swing of 11 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.

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, B6 854 ranged from 85.7% on Wednesday to 93.8% on Friday. With about 49 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why B6 854 runs late

One category carries most of the weight here. Carrier accounts for 57% of the 2,287 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.

Carrier
57%
Late-arriving aircraft
26%
National Airspace System
17%

The largest share of delay minutes, 57%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,295 of the 2,287 delay minutes reported here. The split is drawn from 2,287 delay minutes reported on B6 854.

Cancellations sit at 2.34% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.4% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

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 342 flights under B6 854 in the data flew PBI to JFK. 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. 342 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.
