SYD to BKK Flights

Sydney and Bangkok Airports

When you travel from SYD to BKK, you trade one exciting city for another. Take the Airport Link train from the city centre to Sydney Airport, 8 km south. Disembark at the station under International Terminal 1 and head to the departures level. Trains run every 10 minutes, and the journey takes less than 15 minutes. If you drive to the airport, park in P7 at the International Terminal, a five-minute walk from the gates. Flights from Sydney to Bangkok leave all day except during airport “curfew” between 11p.m. and 6 a.m. (enacted to reduce noise).

When you land at Suvarnabhumi Airport, take some time to marvel at the main terminal roof, which was designed to look as though it floats over the concourse. Take advantage of free Wi-Fi to book car rentals in Bangkok, and head 30 km on Motorway 7 into the CBD. If public transportation is more your speed, choose from the Airport Rail Link (ARL), the suburban commuter train, and air-conditioned buses you can catch from the bus terminal. On the ARL, take Suvarnabhumi Airport City Line (SA City Line), which stops at six stations from the airport, and takes about 30 minutes into the city centre.
