Change just enough money at Suvarnabhumi to reach your hotel, and save the rest for the city. The 24-hour exchange booths in the arrivals hall are convenient, but their rates fall notably short of the branded counters one level down, and well below the exchange shops in central Bangkok. For most arrivals the smartest plan is to swap roughly 1,000–2,000฿ for the taxi and immediate essentials, then change larger sums later where the value is better.
Thailand still runs on cash once you step away from the malls. Metered airport taxis take cash only, toll booths take cash, and most street food and small shops do too. You need baht in hand before you leave the terminal, just not your whole budget.
Airport money options at a glance
| Option | Rate vs city | Fee | Best for |
|---|---|---|---|
| Arrivals hall booth (Level 2) | Weakest | None, but poor rate | A quick 1,000฿ for the taxi |
| Branded counter (Level B, by the rail link) | Close to city | None | A larger cash exchange |
| ATM in the terminal | Interbank, then fees | ~220฿ per withdrawal + your bank | One big withdrawal |
| Exchange shop in the city | Best | None | The bulk of your budget |
Where can you change money inside Suvarnabhumi?
There are two layers of exchange at the airport, and they do not pay the same rate.
The arrivals hall on Level 2 has several currency booths right where you exit customs. They keep long hours, queues are short, and the rate is the weakest you will see on the trip. None of them advertise a commission, because the margin is already built into the board rate. That is fine for a quick swap so you can pay a taxi, and poor value for anything larger.
One floor down, around the Airport Rail Link concourse on Level B (shown on the airport operator's own terminal directory), sit branded exchange counters (the well-known green and orange chains) whose rates run much closer to the interbank benchmark. The walk takes a few minutes and can be worth several hundred baht on a bigger exchange. Counters in the city, around Pratunam and Silom, are usually better still.
To judge how far a booth has drifted, compare its board against the daily reference rate from the Bank of Thailand before you fly. A gap of one to two percent is normal at an airport; five percent or more is your signal to wait.
Should you use an ATM or exchange cash?
Both run 24 hours at Suvarnabhumi, and the maths decides.
Thai ATMs add a flat fee of about 220฿ for every foreign-card withdrawal, on top of whatever your home bank charges. That flat fee is the trap. Five small withdrawals of 4,000฿ cost 1,100฿ in local fees alone, while one 20,000฿ withdrawal pays a single 220฿ fee, about 1.1 percent. Most machines cap a single withdrawal at 20,000–30,000฿, so check your own daily limit before you fly. If you use an ATM, take a larger sum in one go and decline the "pay in your home currency" offer on screen, since that conversion always costs more.
Cash exchange carries no per-transaction fee, so clean hard currency often beats an ATM once you reach a proper counter. Bring US dollars, euros or pounds in good condition and in large notes: a crisp 100-dollar bill earns a better rate than five twenties, and torn or marked notes are turned away. A multicurrency travel card is a third route that sidesteps both the ATM fee and the booth spread, if your bank offers one.
How much cash do you need when you land?
Enough for the ride into town and a small cushion. A metered taxi from the Level 1 public rank to central Bangkok comes to about 350–500฿ all in: the meter fare, a fixed 50฿ airport surcharge, and 25–75฿ of expressway tolls you hand over in cash on the way. The airport taxi cannot take a card, and neither can the toll plazas.
Add a first-day float for food, water and a SIM card, and 1,000–2,000฿ per person makes for a relaxed landing. When you change money, ask for a mix that includes 100฿ and 20฿ notes: a driver rarely has change for a 1,000฿ note on a 350฿ fare, and small notes save an awkward stand-off at the kerb. Riding the Airport Rail Link instead needs almost nothing, as the fare to Phaya Thai is 15–45฿ and the machines take coins and small notes. If you would rather skip the cash question for the ride altogether, a pre-booked private transfer with GetTransfer is agreed and paid by card before arrival, so you walk straight past both the rank and the booth.
How to get the best exchange rate
The usual slip is changing the whole travel budget at the first booth in the arrivals hall, because it is right there and the flight was long. On a $500 exchange that one habit can cost 5–8 percent against a city counter, real money for the sake of ten minutes saved.
Do the reverse. Change a small amount upstairs for immediate needs, then walk down to the Level B counters, or wait for an exchange shop in town for the rest. Keep your passport ready, since counters record larger exchanges, and count the baht at the window before you leave it. On a late arrival your choices narrow, because the city exchange shops have closed and only the airport counters and ATMs stay open, so change just what you need and do the rest in town the next day; the guide to a late-night arrival lays out the 24-hour options.
Paying by card around Bangkok
Cards work only up to a point. Hotels, malls, chain restaurants and convenience stores take them, often by contactless. Markets, street food, songthaews and metered taxis do not. Ride-hailing closes part of the gap: link a card to a ride-hailing app and pay cashless for the car (drivers may still want cash for tolls), or pre-book a private transfer you settle by card before you fly. Cards indoors and a small float of baht for the street is the pattern that holds up. For the rest of your first hour on the ground, including the SIM desk and the official taxi counter, see the Suvarnabhumi arrival guide. Tell your bank you are travelling so a Bangkok withdrawal does not trip a fraud block, and keep a second card in a separate pocket in case one is swallowed.
Frequently asked questions
Is it better to exchange money at Suvarnabhumi Airport or in the city?
Change only a small amount at the airport for your taxi and first day, then exchange the bulk in the city. City counters around Pratunam and Silom pay noticeably more than the arrivals-hall booths on Level 2. The branded counters on Level B, by the rail link, are a fair middle option if you would rather not wait.
How much is the ATM fee at Suvarnabhumi?
Thai ATMs charge about 220฿ per foreign-card withdrawal, plus any fee from your home bank. Because it is a flat charge, one larger withdrawal is far cheaper per baht than several small ones. Decline the on-screen offer to be charged in your home currency, which adds a worse conversion.
How much cash should I bring for the taxi into Bangkok?
A metered taxi to central Bangkok costs roughly 350–500฿ including the 50฿ airport surcharge and tolls, paid in cash. Around 1,000–2,000฿ per person covers the ride plus food and a SIM for the first day. Carry small notes, as drivers rarely change a 1,000฿ note.
Can I pay by card at Suvarnabhumi Airport?
Yes inside the terminal, at shops, restaurants and the rail-link ticket machines. The public taxi and the toll booths are cash only, so change a little money on arrival even if you plan to use cards in the city.
