Hartsfield–Jackson Atlanta International Airport now the airport's second largest carrier. In May 2001 construction of an over fifth runway (10–28) began. It was completed at a cost of $1.28 billion and opened on May 27, 2006. It bridges Interstate 285 (the Perimeter) on the airport's south side, making Hartsfield–Jackson the nation's only civil airport to have a runway above an interstate (although Runway 17R/35L at Stapleton International Airport in Denver, Colorado crossed Interstate 70 until that airport closed in 1995).

Bishop International Airport covers 1,550 acres (6 km²) and has two runways: Bishop International Airport is accessible from I-69, I-75/US-23 and I-475 at Bristol Road. The airport is also served by a bus line operated by the Flint MTA, local taxi services, and Uber which operates in the Flint area. Several car rental agencies are available
