Outagamie County Regional Airport Covers an area of 1,638 acres (6.63 km2) at an elevation of 918 feet (280 m) above mean sea level. It has two runways with concrete surfaces: 3/21 is 8,002 feet (2,439 m) by 150 feet (46 m) and 12/30 is 6,501 feet (1,982 m) by 150 feet (46 m). The airport added a new ground level eight-gate concourse in 2000 and renovated the existing passenger terminal, which was designed by architect Paul W. Powers. The architectural theme was representative of the river flowing through the historic paper manufacturing region.
The current terminal was constructed in 1974, with expansions in 1983, 1990, and 1998. The terminal underwent its most extensive renovaton and expansion to date in 2001. Enhancements within this new 30,000-square-foot (2,800 m2) gate area included more spacious seating areas with natural lighting, ambient in floor heating, new passenger paging system, and five aircraft boarding bridges, a 6th gate for larger planes was added later. It cost $10.7 million and was designed by Mead & Hunt, Inc.
In February 2014, the Outagamie County Board voted to rename the airport, "Appleton International Airport", cited as an "economic development initiative" creating a more direct association with travelers' intended destination.
Efforts to change the name have been ongoing. In 1983, the county board rejected a proposal to change the name to "Fox Cities Metro Airport", and three additional name change efforts failed between 2003 and 2011.
