Chippewa Valley Regional Airport (IATA: EAU[2], ICAO: KEAU, FAA LID: EAU) is a public use airport in Chippewa County, Wisconsin, United States. The airport is owned by Eau Claire county and is located 3 nautical miles (5.6 km; 3.5 mi) north of the central business district of the city of Eau Claire, Wisconsin.[1]

It is the largest airport in the 30-county northern Wisconsin area and serves primarily the Chippewa Valley region, operating on a budget approved by a commission equally representing the interests of Chippewa, Dunn and Eau Claire counties.

The airport is mainly used for general aviation and business travel; the Eau Claire-based Menards corporation uses CVRA to base their fleet of aircraft to serve their stores throughout the Midwest. It is occasionally used as an alternative landing site for flights bound for Minneapolis-Saint Paul International Airport. As of December 2022, only one commercial airline, Sun Country Airlines, provides service for CVRA to Minneapolis International.

The airport is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2025–2029, in which it is categorized as a non-hub primary commercial service facility.[3] It is the eighth busiest of eight commercial airports in Wisconsin in terms of passengers served.

## History

[edit]

In 1923, 80 acres (320,000 m2) of land in Putnam Heights were purchased to build an airport. In 1929, Eau Claire Airways was started at the airport, offering training and scheduled taxi service to destinations in Wisconsin and Minnesota.

In 1939, work on a new airport started north of Eau Claire. In 1940, Eau Claire County Airport started operations at its current site. Eau Claire Municipal Airport opened in 1945, while Chippewa Valley Regional Airport was officially opened in 1947 with the arrival of a Northwest Airlines DC-3. At this time, Eau Claire had three airports. Upgrades at Chippewa Valley Regional Airport were made in further decades, with a terminal addition in 1981. Another terminal remodeling and expansion was completed in 2009.[4]

A new $3.9 million 65 feet (20 m) control tower was built in 2005 and opened in November 2006. Passenger loading used to be from the ramp[5] until a jetbridge was installed in the spring of 2011.

In 2015, the Airport Commission Room was renamed the Duax Commission Room after long-time airport supporter and former airport commissioner David Duax.

In July 2024, the airport board voted to support the return of SkyWest Airlines despite the community's overwhelming support for keeping the incumbent carrier, Sun Country Airlines. Sun Country's bid would have continued service to four nonstop destinations from Eau Claire in contrast to SkyWest's one city, Chicago. Sun Country posted the highest number of enplanements seen at the airport in the last 15 years in 2023.

SkyWest previously served the airport as an Essential Air Service provider until November 2022, before choosing to leave the market. If the Essential Air Service bid is approved by the Department of Transportation, SkyWest service would resume with flights to O'hare International Airport on or around December 1, 2024.

## Facilities and aircraft

[edit]

Chippewa Valley Regional Airport covers an area of 1,100 acres (450 ha) at an elevation of 913 feet (278 m) above mean sea level. It has two runways: the primary runway 4/22 is 8,101 by 150 feet (2,469 x 46 m) with a concrete surface and the crosswind runway 14/32 is 5,000 by 100 feet (1,524 x 30 m) with an asphalt/concrete surface.[1]

For the 12-month period ending December 31, 2022, the airport had 18,897 aircraft operations, an average of 52 per day: 88% general aviation, 10% air taxi, 2% military and less than 1% scheduled commercial. In August 2024, there were 91 aircraft based at this airport: 63 single-engine, 10 multi-engine, 15 jet, 2 helicopter and 1 military.[1]

## Airlines and destinations

[edit]

### Passenger

[edit]

On behalf of United Airlines, SkyWest operated 1-2 daily flights to Chicago-O'Hare until 2022. On March 10, 2022, SkyWest announced its intention to end its service into EAU.[6] After the announcement, the Wisconsin Department of Transportation began seeking bids for a new carrier to provide service. Three airlines submitted bids to provide service to the regional airport: Boutique Air, Southern Airways Express, and Sun Country Airlines.[7]

After an endorsement from the airport, as well as a recommendation from the airport commission,[8][9] the United States Department of Transportation selected Sun Country Airlines to provide service to EAU.[10]
