Bangkok BTS & MRT map and fare calculator

No. On 23 June 2026 the Cabinet replaced the 20-baht flat-fare policy with a plan for a common fare of 17 to 45 baht per trip from 1 January 2027, which is not in force yet. Until then everyone, foreign visitors included, pays each line's normal fare, as shown here.

Changing between the BTS Sukhumvit and Silom lines at Siam is one journey. Changing to another operator, such as BTS to MRT at Asok, means paying a second fare. On MRTA lines you get a discount for changing on the same ticket without leaving the gates: 14 baht between the Blue and Purple lines at Tao Poon, and 15 or 14 baht (depending on direction) between Blue and Yellow at Lat Phrao and between Purple and Pink at Nonthaburi Civic Center. The calculator applies these.

Yes on the MRT Blue Line, MRT Purple Line, MRT Yellow Line, MRT Pink Line, Airport Rail Link and SRT Red Lines: tap a contactless Visa or Mastercard at the gate, and tap out with the same card. Not on the BTS (Sukhumvit and Silom lines), where you need a Rabbit card or a single-journey ticket. Some debit cards do not work, depending on the issuing bank.

A common fare capped at 45 baht per trip, with one entry fee across all lines, is planned from 1 January 2027. It is not in force yet, so the calculator does not use it.

For Suvarnabhumi, take the Airport Rail Link from Phaya Thai (change from BTS) or Makkasan (change from MRT Phetchaburi). For Don Mueang, take the SRT Dark Red Line from Krung Thep Aphiwat.
