B6 959 lands a B, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 354 flights, with a median arrival 8 minutes early.

These figures cover 354 flights between July 2025 and June 2026. The median arrival is 8 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 959 flies

B6 959 flies BDL to FLL without a single fixed slot. Its most common scheduled departure was 07:00, used on 181 of 354 flights, with 06:45 (60 flights) and 06:00 (44 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and B6 959 runs 7 points worse at 82.5%. 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 959 quarter by quarter

B6 959 did not run the same all year. Its best quarter was Jul–Sep 2025 at 92.9% on time and its weakest Jan–Mar 2026 at 64.0%, a swing of 29 points on roughly 89 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 959 did best on Tuesday at 88.5% on time and worst on Sunday at 76.0%. Each day rests on about 51 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 959 runs late

One category carries most of the weight here. National Airspace System accounts for 70% of the 2,603 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.

70% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,815 minutes out of 2,603, against a national NAS share of 21%. The split is drawn from 2,603 delay minutes reported on B6 959.

Cancellations sit at 1.69% 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 3.4% 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 1,173 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 354 flights under B6 959 in the data flew BDL to FLL. 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. 354 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.
