AOT was established on September 20, 2002, as a result of the privatisation of the state-owned Airports Authority of Thailand (AAT). At that time, the company was worth 14,285,700,000 baht. The Thai government holds 70% of the company's stock.^{[6]: 39 [3]: 41}During fiscal year 2014 AOT's average daily market capitalization was 282,321 million baht.^[7]: 4

In 2018, it became the most valuable airport operator in the world.^[8] Thailand's 28 regional airports are managed by the Department of Airports, a separate agency.

Thai aviation began in 1911 when Belgian pilot, Van den Born (Van den Born), brought the Orville Wright aircraft to show between February 2–8, 1911 at Sa Pathum Horse Racing Course, now known as the Royal Bangkok Sports Club. After that, Thailand took an interest in having airplanes for defense and transportation. They sent three military officers to study aviation in France on February 28, 1911. Those officers were Major Luang Sakdi Sanlayawut (Sunee Suwanprateep), Captain Luang Arwut Sikikorn (Long Sinsuk), and First Lieutenant Tip Ketuthat.

After having completed their training, they returned with eight airplanes in 1913, which the Thai government had ordered. They also tested the airplane's flight performance in front of the Thai people on December 29, 1913, at Sa Pathum Airport. The army planned to build a specific military airfield and hangars. However, because Sa Pathum Airport was constructed in an unsuitable location, The Royal Thai Army Aviation and Aviation School chose a new location based on the conditions of having a spacious area, high ground, no flooding, and away from the Phra Nakhon area. In the end, Don Mueang was chosen for all those requirements instead of Sa Pathum.

The area chosen became Don Mueang Airport. On the morning of March 8, 1914, the airplanes took off from Sa Pathum Airport for the last time and flew into Don Mueang Airport for the first time. The airport was officially opened on March 27, 1914. In 1940, the Air Force established the Civil Aviation Division to carry out operations on international aviation. Eight years later, it was upgraded from a division to a department. They renovated the Don Mueang Airport to be an international airport and changed the official name to "Bangkok Airport" on June 21, 1955. Subsequently, the National Assembly enacted the Act on Airports of Thailand, B.E. 2522, requiring the establishment of an airport authority. The Airport Authority of Thailand, abbreviated as AAT, was formed from the act and began operation in July 1, 1979. As the successor to AAT, Airports of Thailand considers that date its own founding day.

The Sa Pathum airfield, previously used as the main field, was replaced by the Suvarnabhumi Airport on September 28, 2006. During the same time, AOT came to administrate Suvarnabhumi. In the following years, Bangkok Airport's name was changed back to Don Mueang Airport on March 13, 2007. The Suvarnabhumi Airport's buildings and facilities were renovated to increase efficiency and responsiveness to travelers' needs. Suvarnabhumi Airport became one of the main airports in Thailand which has more than 40 million global travelers each year. It serves around eight airlines.^[9]

The AOT has expanded to four more international regions, namely Chiang Mai, Hat Yai, Phuket, and Chiang Rai.^[10]

Thailand's six AOT airports saw growth in passenger traffic of 21.3% in 2015, setting a new record of just under 110 million passengers. Aircraft movements—take-offs and landings—grew in tandem by 16.6% from the previous year to 727,750. The growth was expected to continue through 2016 with AOT projecting an 11% increase in combined passenger throughput. Air freight moved through the airports remained largely stagnant in 2015, with a marginal 0.63% increase to 1.38 million tonnes, reflecting sluggish global trade.

Six years later, around 20 million people traveled through airports in Thailand in 2021. In that year, the number of people on both international and domestic flights decreased from the previous years due to the COVID-19 pandemic. In an attempt to expand the tourism industry and even domestic air transportation, the Thai government recently announced that visitors from low-risk countries can visit Thailand without being quarantined. Currently, Suvarnabhumi Airport in Thailand registered the highest number of total air passengers among other airports, amounting to approximately 14.6 million passengers from October 2021 to July 2022. In that same period, there were around 36 million passengers in all airports in the country.

In the past,^[when?] Thailand had no plans for airport development planning, thus unable to meet the demand to its full potential. The current plans for improving current airports and constructing new ones involved dividing Thai airports into 4 groups.^[11]

The vision “Airport System Connecting and Driving the Development of the Country” sets out the vision and strategic goals for the 20-year development in line with the 20-year national strategy formulated by the government.

In order to provide a clear and continuous long-term development direction, the development target is set in four phases.
