This summer, Southern Airways Express will begin flying from Lancaster Airport to Dulles International Airport outside Washington D.C. three times a day while also adding new, weekly flights to Nantucket, Massachusetts. With the change, the sole commercial carrier at the airport in Manheim Township will drop its flights from Baltimore, while continuing to fly twice a day to Pittsburgh. âOur new service pattern will make it easier than ever for busy business travelers to enjoy single connections to more destinations all around the world, with the convenience of flying from their hassle-free hometown airport,â said Mark Cestari, chief commercial officer for Southern Airways.
