In 2017, [[Denver International Airport]] was rated by [[Skytrax]] as the 28th-best airport in the world, falling to second place in the United States behind [[Cincinnati/Northern Kentucky International Airport]]. Skytrax also named DIA as the second-best regional airport in North America for 2017, and the fourth-best regional airport in the world.

Three [[general aviation]] airports serve the Denver area. [[Rocky Mountain Metropolitan Airport]] (KBJC) is {{convert|13.7|mi|km|0|sp=us}} north-northwest, [[Centennial Airport]] (KAPA) is {{convert|13.7|mi|km|0|sp=us}} south-southeast, and [[Colorado Air and Space Port]] (KCFO), formerly Front Range Airport, is {{convert|23.7|mi|km|0|sp=us}} east of the state capitol. Centennial Airport also offers limited commercial airline service, on two cargo airlines.

In the past, Denver has been home to several other airports that are no longer operational. [[Stapleton International Airport]] was closed in 1995 when it was replaced by DIA. [[Lowry Air Force Base]] was a military flight training facility that ceased flight operations in 1966, with the base finally closing in 1994. Both Stapleton and Lowry have since been redeveloped into primarily residential neighborhoods. [[Buckley Space Force Base]] is the only military facility in the Denver area.
