The A1 Express Bus picks up passengers right outside the arrival hall and stops at the entrance to two stations: the Mo Chit BTS station (N8 on the Sukhumvit Line) and the Chatuchak MRT station.

The A1 bus runs every 12 minutes from 7:30am to 12 midnight. It takes the expressway, so traffic is free-flowing and you won’t get stuck in a jam. The journey takes roughly half an hour and costs a flat rate of 30 THB.
After alighting from the bus, go down the subway for the MRT or go up the elevated platform for the BTS. It’s best to have small change ready for the ticket machines.
From here, it takes around 20 minutes to Central Bangkok. The single journey BTS ticket costs between 15 and 52 THB. The Bangkok Metro token costs 16 to 42 THB.
