Midwest Airlines plans to launch three daily roundtrip flights in March 2010 from its Milwaukee hub to St. Louis using 37-seat Embraer ERJ-135s.
Midwest previously operated the route through its Midwest Connect network, but cut several smaller markets in 2008 as it reduced staff and shrank its operations.
Milwaukee-based Midwest was purchased by Republic Airways Holdings in July of this year, and Republic's fleet revamp for Midwest includes the operation of 12 37-50-seat ERJ-135s/145s along with 9-10 Embraer E-190s and 12-13 E-170s. Republic also plans to become the owner of Frontier Airlines after its expected exit from bankruptcy later this month, and some of Frontier's Airbus narrowbodies are likely to be based in Milwaukee.
Schedules in Innovata show AirTran currently operates Boeing 717s from Milwaukee to St. Louis along with American Eagle and Chautauqua Airlines, who both operate 50 and 44-seat ERJs. Chautauqua is also a Republic subsidiary, operating as American Connection from St. Louis.
