I don't see how the 44 number can be right. US' current schedule for June has 59 daily BOS mainline departures to just LGA/DCA/PHL/CLT/PHX alone on weekdays. The reporter must have misunderstood something. I could see US cutting all the Caribbean flights, CUN, LAS, and some or all of the Express destinations: but that should lead to, if anything, more hub and shuttle flying, not less.
