Dade-Collier Training and Transition Airport (TNT/KTNT) is a public-use airport located in the western Everglades region of Miami-Dade County, Florida. It was originally developed as a major commercial reliever airport for South Florida but pivoted to its current role as a training and transition facility primarily serving flight training operations. The airport is owned and operated by Miami-Dade County Aviation Department, which also manages Miami International Airport. Its remote location in the Everglades makes it well-suited for flight training, as it minimizes conflicts with commercial air traffic while providing ample airspace. The facility features multiple runways and is used by airlines and flight schools for pilot proficiency training, including simulator transitions and touch-and-go practice. Though it holds an IATA code, TNT does not serve scheduled commercial passenger service. It remains a critical infrastructure asset for aviation training in the southeastern United States.
