How late do the airport buses run?
The airport buses run from 4:30am to 00:30am and the fare is 100B per person. There are four routes running from both Terminal 1 and 2. A1 goes to Silom Road, A2 to Khao San Rd (actually stopping just around the corner on Chakraphong Rd), A3 goes to Sukhumvit and A4 to Hualamphong train station. They dont seem to run quite as frequently as promised. You can find detailed route information in our story on Bangkok’s new airport here.
