The Airport Rail Link is the fastest and cheapest option, taking about 30 minutes to Phaya Thai station. For groups of 3 or more, or with large suitcases, a metered taxi makes more sense.
- Airport Rail Link: board on level B of the airport. It costs a fraction of a taxi.
- At Phaya Thai, change to the BTS to continue to Siam or Asok.
- Taxi: ask the driver to turn on the meter. On top of the meter, you pay the airport surcharge and expressway tolls.
