Greenville Downtown Airport — Greenville, United States

GMU is Greenville Downtown Airport, located close to the center of Greenville, South Carolina, distinct from the larger Greenville-Spartanburg International Airport that handles major commercial airline traffic. GMU primarily serves general aviation, corporate flights, flight training, and charter operations, offering a convenient close-in alternative for business travelers heading directly into downtown Greenville rather than the outlying commercial hub. The airport has a history dating back decades as a community airfield and has seen its surrounding area develop alongside Greenville's growth into a notable business and cultural center in upstate South Carolina. Facilities support smaller jets and turboprops rather than large airliners. Because of the name similarity, GMU is sometimes mistaken for the international airport, though its traffic profile is entirely different.
