I don't see how.

US used to be the biggest airline in BOS in mainline departures (DL always had an edge in passengers carried due to many more wide body aircraft -- for example, DL used to fly L-1011's from BOS to YUL.) US flew non-stop from BOS to every big Florida market, as well as to cities such as IND, CMH, BUF, EWR, YYZ, etc. Not to mention the many mainline flights a day to PIT, some even with a 767, which was a seasonal through flight to and from FRA.

But in the Wolf years, it was decided that every single passenger departing BOS or elsewhere in the Northeast should be funneled through a hub, and most non-stops to other cities were ceased.

Then, when the BOS domicile closed in 2010, US handed all of its BOS-Caribbean business over to B6, on a silver platter, along with its BOS-LAS flights.

Today, US only flies mainline between BOS and PHL, CLT, PHX, and the two Shuttle markets, LGA and DCA. All other destinations from BOS, and even now some of the flights to the hubs, are served by regional airlines.

And I can't even begin to name the many markets that mainline AA served out of BOS, especially when it was a decent sized wide body base, that are no longer on the schedule.

That hardly sounds like a "major player" to me. (And I'm not criticizing the poster to whom I'm replying, but rather the reporter who made this completely uneducated and unsubstantiated claim.)
