Tri-Cities Regional TN/VA Airport (TRI/KTRI) is a public airport located in Blountville, Sullivan County, Tennessee, serving the combined metropolitan area of Johnson City, Kingsport, and Bristol — collectively known as the Tri-Cities region straddling the Tennessee-Virginia border. The airport offers commercial service connecting the region to major hub airports, primarily through American Airlines and its regional partners. It handles both passenger and cargo operations and serves as an important transportation link for a region otherwise distant from large international airports. The facility is owned and operated by the Tri-Cities Airport Authority and has undergone various infrastructure improvements over the years to modernize its terminal and runway capabilities.
