Lot Polish Airlines and JetBlue will expand their interline agreement to include codesharing, Lot announced. Passengers on either airline this winter season will be able to book their entire route with a single ticket, a uniform baggage policy and fare conditions, according to Lot. The carriers did not specify the date on which they would begin codesharing. U.S. passengers will have access not only to Polish cities, but also to other destinations in Central and Eastern Europe, Lot network department director Robert Ludera said in a statement.
