Airports in Grant County, Washington

Grant County, Washington sits at the heart of the Columbia Basin, a high-desert plateau stretching across central Washington state. With an economy anchored by irrigated agriculture, manufacturing, and data centers powered by abundant hydroelectric energy, Grant County depends on reliable air service to connect its residents, businesses, and visitors to regional and national destinations. The county's primary aviation gateway is Grant County International Airport (MWH), a full-service commercial and general aviation facility that serves the entire region.

Grant County International Airport, located adjacent to the city of Moses Lake, operates one of the longest runways in the Pacific Northwest at 13,503 feet. Originally constructed as Larson Air Force Base during World War II and subsequently expanded during the Cold War, the airport's military heritage left behind infrastructure that today makes it uniquely valuable for specialized aviation operations. Boeing regularly uses the extended runway to conduct flight testing and delivery operations for new aircraft, taking advantage of the dry climate, low air traffic congestion, and exceptional runway length that few civilian airports in the United States can match.

Commercial passenger service at MWH has historically been provided through Essential Air Service (EAS) subsidies, reflecting the county's rural character and the distance from major metropolitan hubs. Travelers flying out of Moses Lake have accessed connections through Seattle-Tacoma International Airport (SEA) and other regional gateways. The airport's terminal facilities support both scheduled commercial flights and the significant charter and corporate aviation activity generated by Boeing's ongoing presence.

Beyond Moses Lake, Grant County is home to several general aviation airports that serve agricultural operators, private pilots, and emergency services. Ephrata Municipal Airport (EPH), located approximately 14 miles northwest of Moses Lake in the county seat of Ephrata, provides a reliever airport for smaller aircraft and serves the local agricultural community. Crop dusters, survey aircraft, and private planes use Ephrata Municipal for operations across the Columbia Basin's vast farmlands, where center-pivot irrigation systems support potato, wheat, corn, and hop production across hundreds of thousands of acres.

Quincy Municipal Airport (77S) serves the western portion of Grant County near Quincy, a community that has grown significantly due to the expansion of major data centers operated by companies including Microsoft, Intuit, and Dell. The airport provides general aviation access for corporate travelers visiting these facilities, which have transformed Quincy into one of the most data-dense communities per capita in the United States.

The Royal City Airport (RYN) in the southern part of the county offers another general aviation option, primarily serving agricultural operators in the Royal Slope and lower Columbia Basin farming areas. Additional private and agricultural airstrips are scattered throughout the county's 2,791 square miles, reflecting the practical aviation needs of farming operations spread across this vast landscape.

Grant County's aviation infrastructure is overseen by the Port of Moses Lake, a public development authority that manages Grant County International Airport and promotes economic development throughout the region. The port actively recruits aerospace and manufacturing businesses that benefit from the airport's unique runway capabilities and available industrial land adjacent to the airfield. Several aircraft maintenance, repair, and overhaul (MRO) operations have established facilities at MWH, drawn by the favorable operating environment and the airport's established relationship with Boeing.
