Phu Bai International Airport — Huế, Vietnam

HUI is Phu Bai International Airport, serving the historic city of Huế in central Vietnam, former imperial capital of the Nguyen Dynasty. Located south of the city, HUI connects Huế to Hanoi, Ho Chi Minh City, and other domestic destinations, supporting tourism to the city's UNESCO-listed Imperial City, royal tombs, and nearby former demilitarized zone sites from the Vietnam War. Despite its international designation, HUI primarily handles domestic traffic, with international charter and seasonal services being less common. The airport has undergone terminal upgrades to accommodate rising visitor numbers drawn to Huế's cultural heritage and its proximity to Da Nang and Hoi An along Vietnam's central coast.
