The booth landscape
Exchange counters run throughout Suvarnabhumi: bank booths line the arrivals and departure levels, and independent counters operate on the B1 level by the rail-link entrance. The widely established pattern holds here — rates airside and in the immediate arrivals hall are generally less favourable than landside counters and city rates, because convenience is priced in.
A practical approach: change only what the first day needs at the most convenient counter, then compare the B1-level counters or city branches for the serious amount. Rates are posted openly, and comparing costs nothing.
ATMs and the foreign-card fee
ATMs are plentiful in every zone. Thai bank machines add a fixed operator fee per withdrawal on foreign cards — ฿220 (~$7) was the standard figure for years, and many machines now display higher amounts depending on the bank and card network. The machine shows the exact fee on screen before you confirm; read that screen and cancel if you do not accept it.
Two rules travel well: decline dynamic currency conversion — always choose to be charged in baht — and make fewer, larger withdrawals rather than many small ones, since the fee is flat per transaction. Your own bank’s foreign-use charges stack on top; check them before travelling.
Cards, cash and the onward journey
Cards are widely accepted at airport shops, hotels and larger city businesses, but the onward journey runs on cash more often than visitors expect: public taxi meters, tolls paid through the driver, bus fares and street food are cash-first. Keep small notes — a ฿1,000 (~$30) note is awkward at a taxi meter.
Carrying large sums? Thai Customs rules govern the currency amounts that must be declared — check the current thresholds on the customs source below if you travel with substantial cash.
Checklist
- Only the first day’s cash changed at the most convenient counter
- On-screen ATM fee read before confirming — and DCC declined
- Small notes kept for taxis, tolls and food
- Customs currency rules checked when carrying large amounts

Frequently asked questions
Should I exchange money airside at BKK or wait?
Change the minimum airside. Landside counters — especially at the B1 rail-link level — and city branches generally post better rates; the pattern is consistent enough to plan around.
How much is the ATM fee for foreign cards?
It is a fixed per-withdrawal operator fee set by the Thai bank: ฿220 (~$7) was the long-standing standard, and some machines now show more. The exact figure appears on screen before you confirm — that screen, not any guide, is the authority.
