Utapao International Airport

U-Tapao International Airport is a joint civil-military public international airport in Thailand, serving the cities of Rayong and Pattaya in Eastern Thailand. It also serves as the U-Tapao Royal Thai Navy Airfield and is home to a large Thai Airways maintenance facility. The airport was built by the United States to accommodate B-52 bombers during the Vietnam War, and it briefly became Thailand's main international gateway in 2008 when Bangkok's airports were occupied by protesters. The airport has since undergone expansion plans to increase its capacity from 800,000 to 60 million passengers per year, with a new second terminal opening in 2019 and a further expansion plan approved in 2022.learn more on wikipedia
