## Who AOT is

Airports of Thailand Public Company Limited is the airport operator commonly identified by the initials AOT. It was formed through the corporatization of the Airports Authority of Thailand in 2002 and is listed on the Stock Exchange of Thailand under the symbol AOT.

AOT operates under the supervision of Thailand’s Ministry of Transport, while the Ministry of Finance is its largest shareholder. For passengers, the most important point is practical: AOT manages the airport environment and coordinates the facilities through which millions of domestic and international journeys pass.

## The six airports operated by AOT

The AOT network covers three airports available through airporthai.com and three additional regional gateways.

- Suvarnabhumi Airport (BKK)—Thailand’s principal international aviation hub.
- Don Mueang International Airport (DMK)—a major Bangkok gateway for domestic and international travel.
- Phuket International Airport (HKT)—the principal air gateway for Phuket and the Andaman coast.
- Chiang Mai International Airport (CNX).
- Hat Yai International Airport (HDY).
- Mae Fah Luang–Chiang Rai International Airport (CEI).

## What an airport operator coordinates

An airport journey depends on far more than the runway. AOT’s role spans airport infrastructure and capacity, passenger terminals, safety and security coordination, ground access, commercial areas, information channels and collaboration with airlines, government agencies and operating partners.

Some decisions remain with airlines, immigration, customs, security authorities or individual service operators. That is why passengers should use the matching authority for a changing rule, while using the current airport portal to organise the overall trip.

## Where airporthai.com fits

airporthai.com is the current digital entry point for the AOT airport websites in Phuket and Bangkok included in this portal. It connects each airport’s passenger information, live flight lookup, local guides and direct official AOT VIP Fast Track booking without forcing travellers to assemble the journey from unrelated pages.

For general AOT corporate information, reports or group-wide announcements, the AOT corporate channels remain the specialist reference. For HKT, BKK or DMK passenger planning, choose the matching current airport website here.
