As of April 8, Delta will expand service in upstate New York with 22 new Delta Connection flights between Ogdensburg, Watertown, Albany, and Massena to Boston. Many of these cities were formerly US Airways monopolies. For those traveling within New York State, service will be available between Albany and Watertown with continuing service to Ogdensburg and Massena. Big Sky Airlines, which currently serves 18 cities in Montana, Idaho, Wyoming and elsewhere, has partnered with Delta to operate these routes.
