U-Tapao International Airport also spelled Utapao and U-Taphao, is a joint civil–military public airport serving Rayong and Pattaya cities in Thailand. It is in Ban Chang District of Rayong Province.It also serves as the U-Tapao Royal Thai Navy Airfield, home of the Royal Thai Navy First Air Wing. U-Tapao is the home of a large Thai Airways maintenance facility, servicing that airline's aircraft as well as those of other customers. Due to the blockade of Bangkok's airports by opposition protesters, U-Tapao briefly became the main air gateway to Thailand between 26 November and 5 December 2008. As both of Bangkok's international airports essential to the country's tourist boom are operating beyond capacity as of 2015, U-tapao in particular has been eyed as an alternate international gateway due to relative proximity to the capital.LocationU-Tapao lies approximately 90mi southeast of Bangkok, south of Rte 3 (Thanon Sukhumvit) at km189, near Sattahip on the Gulf of Thailand, about a 45-minute drive from Pattaya (Thailand's most popular beach resort).
