Republic Airways is seeking to shift the destination on two slots between Washington's National airport and Milwaukee to Madison, Wisconsin, and Omaha, Nebraska.
The Indianapolis-based carrier would use the slots to maintain once daily service between National and both Madison and Omaha if the shift is approved, according to a regulatory filing.
Republic would end flights between Washington and Milwaukee, a market it inherited when it bought Midwest Airlines in 2009, if the shift is approved.
The flights are operated for Republic-subsidiary Frontier Airlines.
Frontier and Republic have drawn down the former Midwest hub in Milwaukee in recent years. The carriers will only fly to Cancun, Denver, Orlando and Rhinelander from the city if application is approved.
Michael Boyd, chairman of the Boyd Group International, says that Milwaukee has lost its status as a connecting point in the USA and that he expects to see declining passenger enplanement numbers at the airport during the next five years, at the Boyd Group International Aviation Forecast Summit in Dallas today.
Southwest Airlines-subsidiary AirTran Airways flies between Washington National and Milwaukee, according to Innovata schedules.
