Air Wisconsin was the launch customer for the BAe 146, and took delivery of its first aircraft, series 200 N601AW, in June 1983. It later also launched the series 300, which it placed into service in 1989. Air Wisconsin’s BAe 146 fleet reached an all-time high of 18 aircraft in 2002, all of them operated on behalf of United Express. The fleet had to be wound down after bankrupt United Airlines dropped Air Wisconsin from the United Express network in a cost-cutting move. The airline retired its last 146s in April 2006.
