With and a main runway, it is one of the largest airports in the United States. Moses Lake is famous for good flying weather, as it is located on the east side of the
Cascade Range, in the semi-arid desert of
central Washington. Grant County International Airport was an alternate landing site for the
NASA Space Shuttle. Scheduled passenger flights on
Big Sky Airlines to
Boise and
Portland were discontinued on September 1, 2006. The service was subsidized by the
Essential Air Service program. United Express, operated by
SkyWest Airlines offered nonstop flights to
Seattle from June 2009 until June 2010. The airport currently has no commercial passenger air service. The airport was used for heavy jet training by
Japan Airlines (JAL) for over forty years, until the closing of their training offices The airport also had been used for flight testing of the
Mitsubishi SpaceJet. In November 1974, the airport hosted a new
Supersonic Transport (SST)
Concorde for a month during
FAA certification testing. It is also utilized by the
U.S. Air Force and
Boeing as a testing facility. Most of the traffic at the airport is general and military aviation. In 2011, the
92nd Air Refueling Wing at
Fairchild AFB in Spokane temporarily moved its
KC-135 R/T fleet and operations to Moses Lake while Fairchild's runway underwent reconstruction and other infrastructure improvements, to include an upgrade to the base's aviation fuel distribution system. The main campus for
Big Bend Community College is also located on the grounds of the airport. After the grounding of all Boeing 737 MAXs from March 2019, approximately 50 of the grounded airplanes were parked at the airport. This was originally seen as an economic opportunity for the airport, but later caused concern as the number of planes stored kept increasing, to approximately 130 by October 2019. == Facilities and aircraft ==
