Knoxville McGhee Tyson Regional Airport is just over an hour from Gatlinburg, and just under an hour from Pigeon Forge.
Because it is a regional airport, the TSA checkpoints are usually short so wait times are not as long as international airports. It also means international travelers may need to transfer from a larger airport to get to this one. Airlines that travel to this airport include Delta, American, Allegiant, and United. This is the most popular airport for those who fly into Gatlinburg.
