These figures cover 354 flights between September 2025 and August 2026. The median arrival is 4 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.

Across the year
B6 959 quarter by quarter
B6 959 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.9% on time and its weakest Jan–Mar 2026 at 64.0%, a swing of 24 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.

5 of 24 late departures made up the time and arrived on time, 21% of them. In the other direction, 46 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at FLL.

Delay causes
Why B6 959 runs late
National Airspace System accounts for 64% of the 2,927 delay minutes carriers reported here, and the remaining four split what is left.
- 64%National Airspace System
- 28%Carrier
- 8%Late-arriving aircraft
- 1%Extreme weather
64% 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 1,868 minutes out of 2,927, against a national NAS share of 21%. The split is drawn from 2,927 delay minutes reported on B6 959.
Cancellations run at 2.82%, against 1.89% nationally. That is roughly one flight in 40 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
Badly late arrivals are rare here: only 4.1% land an hour or more behind schedule, against 8.3% 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.
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.
What to do with this
Booking B6 959
For a booking, the cancellation rate is the figure to plan around on B6 959: 2.82% of its 354 scheduled flights did not operate. A late arrival costs about 45 minutes, but a cancellation costs the day, so leave a later option open.
