Delta Air Lines makes changes in Boston, adding routes where it has positions of strength

A modest push by Delta Air Lines out of JetBlue's fortress in Boston during 2014 raised questions about the mega airline's intentions for Boston, and if its moves signalled heightened competition with the airport's largest airline JetBlue.

Over a year later the two airlines appear to be coexisting peacefully in Boston, leveraging their respective strengths as the airport's two largest airlines. JetBlue has roughly 125 daily departures from the airport, pushing forward to its goal of 150.

Delta, meanwhile, appears to be making minor changes in Boston, leveraging new markets where it has areas of strength and shedding routes that may not be working within the larger context of its network.
