  • What airports serve Adelaide to Bangkok?

    When flying from Adelaide to Bangkok, you will use Adelaide International Airport (ADL) and arrive in Suvarnabhumi Airport (BKK). Adelaide Airport is one of the busiest airports in Australia and close to the city centre, approximately 6 km out of Adelaide central, making it convenient to reach by public transport. When you arrive in Bangkok, you will land at what is one of the largest airports in Southeast Asia, Suvarnabhumi Airport, also known as Bangkok Airport. The airport is approximately 30 km away from the Bangkok city centre, which can best be reached by the Airport Rail Link City Line, which runs directly into town, or the Bangkok Elevated Road and Train System. Bangkok is notoriously congested on the roads so expect to travel a little longer than usual if you opt for a taxi.
