Because trains are often filled to the brim we suggest taking the shuttle bus a taxi into the city if you are loaded with luggage. But if you are traveling light, the Suvarnabhumi Airport Rail Link (SARL) is a convenient and cheap way of transferring from the airport to many locations within Bangkok and link up with the BTS skytrain and MRT underground. Traveling from the airport tickets are bought on the ground floor of the airport terminal.
The rail link offers 3 travel options; the city line, Paya Thai Express and Makkasan Express line. We briefly discuss each option.
City Line Commuter Train

Phaya Thai Direct Express Line
If you need to commute between the city and airport faster the Phaya thai express line travels direct without any of the stops mentioned above. One way travel time is 15 minutes and cost 90 Baht one way or 150 Baht for a round trip.
Makkasan Direct Express Line
