Bangkok’s Airport Rail link is most convenient and cost effective way to get to Suvarnabhumi International. The line runs through Bangkok city center. It has only 8 stops. It takes approximately 40 minutes at most to get to the airport (Google for some strange reason thinks it takes 2 1/2 hours) from the beginning of the line. It’s scheduled for 1 train every 10 minutes ( it did as we were leaving on a Sunday of H. M. Birthday on July 28). At 35 Baht = $1.25 U. S. it can’t be beat on cost. There are buses/subways that can take you to the various stations and each station is about 2-3 miles apart. Unfortunately it is a cash only system and tokens can be bought at the kiosk on the platform. There are elevators and stairs to the platforms at the stations.

Only 45 Baht one way to/from BKK Airport to city centre (BTS Phaya Thai). 30 minute journey with 7 stops. Open daily 5.30-24.00... We found queues at ticket booth were shorter and faster than ticket machines when we were there on Friday late afternoon so we just walked straight to the ticket booth. Pretty busy tho. I reckon you stay at a hotel near BTS Phya Thai if you have suitcases. Easier to travel around Bangkok. We stayed at Hotel Thomas Bangkok. Short stroll from Airport Rail Link and BTS. Quite new and inexpensive. P.S. Avoid peak hours in the morning, late afternoon thru evening during weekdays if possible. Massive queues and way too busy.

Airport Rail Link is an easy way to get to/from Suvarnabhumi Airport. Airport Rail Link departs from the basement at Suvarnabhumi Airport, and city line stop at Lad Krabang, Ban Thap Chang, Hua Mark, Ramkhamhaeng, Makkasan where you can interchange with MRT Blue Line from Phetchaburi Station, Ratchaprarop – Phayathai where you can interchange with BTS Sukhumvit Line at Phayathai Station. The fare between Suvarnabhumi Airport and Phayathai is just 45 baht.

This is my default mode of transport out of Suvarnabhumi (I think pronounced Suwanapoon) airport. Gets you downtown pretty quickly (you avoid traffic) and cheaply (much cheaper than taxis, avoid paying tolls). B35 to Makkasan from which you can transfer to the subway at Petchaburi. P45 to Phayathai from which you can transfer to the BTS. The transfer from Makkasan to Pethaburi is a bit more inconvenient. When you get off at Makkasan, there's a walk to Petchaburi station (good directional signs). I suggest you take the 2 lifts if you have heavy luggage coz there are stairs going to Petchaburi station. Phayathai is more straightforward because you don't have to walk too far or go street level to reach the BTS.

Bangkok's airport train is on the lowest floor of the airport, easy to reach via a series of lengthy travelators, or lifts. The fare to Lat Krabang (one stop) was a bargain THB 20 (less than A$1). My train promptly departed. It was airconditioned and fairly fast. Not all stations are totally step free, but this only applied at Lat Krabang to the last bit before the road: about 24 steps if I recall. I could easily toddle my suitcase down that flight. An excellent alternative to what can be congested roads.

This service called city line can be availed at the basement level of Suvarnabhumi (BKK) airport. Tickets can be purchased on the spot. The machine accepted Thai Baht in the denominations of 100, 20 and 10 for a tokenised travel. I was charged 45 THB to Phaya Thai. Is a convenient, pocket friendly and time saving service.

It is literally an elevated railway that runs from Airport to Bangkok. It's quick and comfortable. The difficulty is that transferring to the Skylink or subway is not convenient. Tickets are not linked. The same station has a different name. No escalator. Taxis may be better for travelers with large luggage.

We started off from Lumphini station. Took the MRT to Phetchaburi station. Walked to interchange station Makkasan for Sky train to the airport. Signs and notices are very clear. Followed the crowd lots of people going the same way. We were at the airport under an hour. We are both over 70. Although we only have hand luggage not heavy. Much cheaper than taxis.
