Delay causes

Why B6 144 runs late

Late-arriving aircraft accounts for 45% of the 4,662 delay minutes carriers reported here, and the remaining four split what is left.

45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,662 reported delay minutes here, that single category outweighs weather by 45 to one. The split is drawn from 4,662 delay minutes reported on B6 144.

Cancellations run at 5.24%, against 1.89% nationally. That is about one flight in twenty 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

11.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.

Every one of the 267 flights under B6 144 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. 267 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 144

For a booking, the cancellation rate is the figure to plan around on B6 144: 5.24% of its 267 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
