Facing a possible loss of contracts to fly for US Airways, Mesa Air Group signed codesharing deals with Delta Air Lines and United Airlines. Starting in October, Mesa will operate up to 30 Bombardier CRJ200s in Delta's network and 30 under the United Express name. Mesa will now place jets that could have been bumped from US Airways contract flying under recent deals that US Airways signed with both Air Wisconsin and Republic Airways.
