Tampa International Airport — Tampa, United States

TPA opened its current terminal complex in 1971 with a design that became influential across the industry: a central landside building connected by automated people-movers to separate airside concourses where aircraft actually board. That layout, unusual for its time, kept walking distances short and has repeatedly earned the airport high marks in traveler satisfaction surveys over the decades since. It serves the greater Tampa Bay area, including St. Petersburg and Clearwater, and sits close to Tampa's cruise terminals, MacDill Air Force Base, and the city's downtown core. Major domestic carriers operate substantial schedules here, and international routes reach destinations in the Caribbean, Latin America, Canada, and parts of Europe. Florida's tourism economy, along with a steady stream of business travel tied to the Tampa Bay region's finance, healthcare, and technology sectors, keeps passenger volumes among the highest in the southeastern United States.
