Took the train to the airport on 04 July and was amazed just how easy it was.
Boarded the BTS at E2 and travelled to N2 where I transferred to the airport train. For THB45 the airport train was well worth it and I'll definitely do it again.
Going from the basement to the departure area is a slight inconvenience but nothing insurmountable.
I travel alone with HLO so it works for me and no taxi stress makes it even better.As a regular visitor to BKK I do know how to use the BTS so this helps getting to the transfer station.
