What Airports of Thailand does

Airports of Thailand Public Company Limited (AOT) is a state-owned airport operator listed on the Stock Exchange of Thailand under the ticker AOT, with the Government of Thailand as the controlling shareholder. The company operates Thailand's six major international airports—Suvarnabhumi (BKK), Don Mueang (DMK), Phuket (HKT), Chiang Mai (CNX), Mae Fah Luang–Chiang Rai (CEI), and Hat Yai (HDY)—handling 125.99 million passengers and 788,095 flights across the network in FY2025. Suvarnabhumi alone accounts for over 62 million passengers annually, making it the country's primary international hub and one of the largest airports in Southeast Asia.

AOT's service portfolio spans core airport operations (passenger screening, security, customs, immigration), ground aviation services, and commercial property leasing at airport terminals. The digital layer includes the Sawasdee by AOT mobile application that connects all six airports, plus biometric processing technology deployed at Suvarnabhumi for faster passenger identification. The company is executing an 80 billion baht five-year capital expansion program covering Suvarnabhumi East Expansion, Don Mueang Phase 3, Suvarnabhumi infrastructure upgrades, and Phuket second-phase expansion, with a broader 210 billion baht Suvarnabhumi expansion pipeline.

AOT's revenue model is dual-stream: aeronautical revenue (landing charges, passenger service charges, aircraft parking, terminal fees) totaled 33.05 billion baht in FY2025, growing 6.6% YoY, while non-aeronautical revenue (duty-free, retail, F&B, advertising, parking) totaled 33.63 billion baht but declined 6.89% YoY. Total FY2025 revenue reached 68.59 billion baht with net profit of 18.13 billion baht. Effective June 20, 2026, AOT raised the international departure passenger service charge by 53% from 730 to 1,120 baht, generating an estimated 10 billion baht in additional annual revenue to fund expansion. Customer segments span international airlines (Vietnam Airlines, flydubai, Norse Atlantic, British Airways, Air Canada among others), commercial tenants (King Power is the flagship duty-free partner), and ultimately 125+ million end-passenger travelers annually.
