The Bangkok Airport Rail Link (ARL) offers the fastest, most reliable, and most economical transit method connecting Suvarnabhumi International Airport (BKK) directly to downtown Bangkok. Operating along a 28.6-kilometer elevated rail viaduct, the ARL bypasses surface highway gridlock entirely.

The journey between the airport terminal and the western terminus at Phaya Thai takes 26 to 30 minutes, with one-way fares ranging from 15 to 45 THB (approx. $0.45 to $1.30 USD).

  • Currency for Kiosks: Automated ticket machines accept 20, 50, and 100 THB banknotes along with 1, 5, and 10 THB coins. Staffed booths can break larger 500 and 1,000 THB notes.
