The Central Wisconsin Airport (CWA) is a regional non-hub airport located in Mosinee, WI roughly equidistant between Stevens Point and Wausau.  The airport is owned by Marathon and Portage Counties and is governed by the Central Wisconsin Joint Airport Board.  It is currently served by two airlines, Delta and American.

CWA first opened in 1969 with 39,000 departing passengers annually.  A concourse renovation took place in 1998, which equipped the airport with five departure gates and four boarding bridges.  CWA broke ground in spring of 2011 on a terminal renovation and expansion project aimed at increasing operational space, expanding the security checkpoint, expanding parking facilities, and relocating car rentals to their own facility.  In 2020, the concourse was remodeled to better serve passengers with new state-of-the-art restrooms, the addition of privacy rooms, a kitchen build-out to allow for additional food options at the cafe, new gate area seating, and the installation of charging stanchions throughout the concourse area.   

​

In 2019, enplaned passengers neared 145,000 with continued growth anticipated.  Upcoming projects include completion of the Master Plan project and rehabilitation of Runway 17/35.
