Frontier Airlines says it will cut 11 flights out of Milwaukee and put 125 workers on furlough effective June 1.
Flights on the chopping block include nonstop service from Milwaukee to New York LaGuardia, Columbus, Indianapolis, Nashville, Omaha and Pittsburgh.
The Milwaukee Journal-Sentinel reported the airline will still have direct flights from Milwaukee to Denver, Orlando, Washington, D.C., and Rhinelander, Wisc.
Frontier has steadily lost market share at Milwaukee since it took over Midwest Airlines in 2009.
Frontier's parent company is Indianapolis-based Republic Airways Holdings.
