Indianapolis-based Chautauqua Airlines has transferred the last of its once 23-strong fleet of Embraer 170 jets to its sister carrier, Shuttle America. The move relieves parent company Republic Airways of penalties it has had to pay American Airlines for scope-clause violations. The contract signed by American and its pilots prohibits any American Connection carrier from flying jets that hold more than 50 seats for any partner. Chautauqua, which flies Embraer ERJ140s as American Connection, had flown the 70-seat Embraer 170s for Republic since the airplane’s introduction in April last year.
