These figures cover 311 flights between September 2025 and August 2026. The median arrival is 5 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.

Delay causes
Why B6 1142 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 2,966 reported delay minutes.
- 40%Late-arriving aircraft
- 39%Carrier
- 20%National Airspace System
- 1%Extreme weather
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,966 reported delay minutes here, that single category outweighs weather by 37 to one. The split is drawn from 2,966 delay minutes reported on B6 1142.
Cancellations run at 2.57%, against 1.89% nationally. That is about 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
5.6% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The 1,133 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 311 flights under B6 1142 in the data flew PBI to BDL. 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. 311 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 1142
For a booking, the cancellation rate is the figure to plan around on B6 1142: 2.57% of its 311 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
