The short answer

At Suvarnabhumi (BKK), skip the arrivals-hall booths. Use an ATM with a low-fee card, or follow the "Train to City" signs down to the basement (B) floor, where private exchange counters next to the Airport Rail Link station pay close to city rates for major currencies.

At Don Mueang (DMK), where most budget and domestic flights land, there's no specialist counter inside the terminal. Use an ATM, or change only enough for your journey.

Bringing rand? Keep most of it for Bangkok's specialist head offices on Ratchadamri Road, which paid ฿2.03 per rand on 22 October 2026. We couldn't confirm a published rand rate at either airport.

Suvarnabhumi Airport (BKK): where to exchange

Suvarnabhumi is where flights from South Africa land — one-stop connections through the Gulf, Ethiopia, Singapore and Hong Kong. After immigration and baggage reclaim, you come out into the arrivals hall on Level 2.

Level 2 — the arrivals hall

The exchange booths here are run by Thai banks. They're open around the clock, they're the first thing you see, and they pay the least — independent comparisons put airport bank booths at around 3% to 7% below the mid-market rate for major currencies. On R5,000 of US dollars, that's R150 to R350 handed over for the convenience. And for rand, you may find no rate on the board at all.

They have their place: if you land in the middle of the night with no working card, change just enough for a taxi.

Floor B — by the Airport Rail Link

Go down two levels from the arrivals hall, following the "Train to City" signs, then the currency exchange signs. In the corridor next to the entrance to the Airport Rail Link station, you'll find a row of private exchange counters. The best known is SuperRich — specifically SuperRich 1965, the orange-branded company, which runs the airport branch (the green SuperRich Thailand closed its airport counter). Several competing changers sit alongside it.

The SuperRich airport counter is open daily from about 5:30am to 11:30pm. For popular currencies such as US dollars and euros, rates are typically within about 1% of mid-market. SuperRich 1965 buys rand at its city branches — its ICONSIAM branch paid ฿2.00 on 22 October 2026 — but airport rates for less common currencies can be wider, so check the board before you hand over rand. The bank counters on the B floor pay less; walk past them to the private changers.

You'll need your passport. Count your baht at the window and keep the receipt.

ATMs at Suvarnabhumi

There are plenty of ATMs at Suvarnabhumi, run by Bangkok Bank, Kasikornbank, Krungthai, Krungsri, SCB and others. You'll find clusters in the arrivals hall on Level 2 and on the B floor near the Airport Rail Link, plus more on the departures level.

Every one of them charges a foreign card a fee — typically ฿220 per withdrawal, about R108 — on top of whatever your South African bank charges. There's no fee-free ATM at the airport for a South African card.

Using an airport ATM is a good choice if:

• Your card has low fees abroad — Capitec and GoTyme charge R70, Bank Zero R10 per R1,000 (minimum R50), with no conversion fee on withdrawals from Capitec or GoTyme.
• Your daily limit is high enough — a ฿20,000 withdrawal is about R9,900 with the Thai fee. Set a temporary limit in your banking app before you fly.
• You withdraw a decent amount — on Capitec, ฿20,000 at once costs about 1.8% in fees; ฿3,000 costs about 12%.
• You decline conversion — when the screen offers to charge you in rand, choose "decline" or "without conversion".

It's a poor choice on a big-bank card, which typically adds 2.75% plus a per-R100 cash fee — about R285 on ฿10,000 at Standard Bank pricing, before the ฿220. If that's what you've got, withdraw the largest amount you can, once.

Don Mueang Airport (DMK)

Don Mueang, Bangkok's older airport to the north of the city, handles budget airlines — AirAsia, Thai Lion Air, Nok Air and others — on domestic routes and flights around Asia. You'll arrive here if you connect through Kuala Lumpur or another regional hub on a low-cost carrier, or fly in from a Thai island.

Exchange options inside the terminal are limited. There's no SuperRich at Don Mueang; the counters in the arrivals hall and the bank booths before immigration tend to offer similar rates — reported at around 5% below mid-market for major currencies.

A better option sits just outside the terminal. Happy Rich, a private exchange company, has a branch next to the SRT Red Line Don Mueang station, reported to open from about 5am to 10pm. Its rates are reported to be several percent better than the terminal bank booths for major currencies. We couldn't confirm a rand rate there.

The rest of the advice is the same: use an ATM with a low-fee card, or change only what you need for the journey.

Airport options compared

What each option costs for about ฿10,000 (about R4,900) at ฿2.04 to the rand. Scroll sideways on a phone.

ATM costs from each bank's 2026 pricing guide plus the Thai ฿220 fee. Counter margins are typical published figures for major currencies (thaiest.com, travelcurrencyguide.com, 2025–2026); we couldn't confirm published rand rates at either airport. Check the board on the day.

How much baht you need when you land

Less than you might think. Most of what you'll pay for in your first few hours can be paid by card, and the main cash cost — getting into town — is modest.

Getting from Suvarnabhumi into Bangkok

The Airport Rail Link costs ฿15 to ฿45 to Phaya Thai and runs roughly 5:30am to midnight. Since November 2025 you can tap in and out with a contactless Visa or Mastercard at marked gates, so you don't need cash at all — your South African card works if it's contactless and enabled for international use. Public taxis leave from the counters on Level 1: you pay the meter, plus a ฿50 airport surcharge and any expressway tolls, and a trip to central Bangkok typically comes to around ฿300 to ฿500. Most drivers want cash, and tolls are paid at the booth as you go, so have some ฿20 and ฿100 notes. Grab and Bolt offer set prices, payable by card in the app, and are often similar to a metered taxi.

Getting from Don Mueang into Bangkok

At Don Mueang, airport buses A1 and A2 cost ฿30 and A3 and A4 ฿50, paid on board in cash or by Visa or Mastercard. The SRT Red Line runs from the station across the skywalk into Bang Sue, with connections to the MRT, and public taxis work as at Suvarnabhumi: the meter plus surcharge and tolls.

Add a drink, a snack and perhaps a Thai SIM or eSIM (the counters accept cards), and ฿1,000 to ฿2,000 covers most arrivals comfortably. If you're arriving late at night, heading straight to an island, or travelling as a family, aim for the upper end — or simply withdraw ฿20,000 once and you're set for several days.

You may also want cash to show if Thai immigration asks for proof of funds — officially ฿20,000 per person or ฿40,000 per family — although few visitors are asked, and a recent bank statement may also be accepted. Our guide to how much cash to bring from South Africa covers this in detail.

Airport money traps to avoid

Airport ATMs will offer to convert your withdrawal to rand; always decline, because it typically costs 6% or more extra. Don't exchange all your money in the arrivals hall — change a taxi fare at most, then use an ATM or go downstairs or into town — and set a temporary daily limit in your app before you board, because if your card's limit stops you taking ฿20,000 you'll pay the fees several times. Ignore taxi touts inside the terminal and use the official public taxi counters on Level 1, the limousine counters (more expensive, but fixed and legitimate) or a ride-hailing app. Public taxis from the official rank must use the meter, with the surcharge and tolls the only extras. Airport card machines may offer to charge you in ZAR, so choose baht. And avoid small withdrawals: at ฿220 plus your bank's fee each time, a ฿2,000 withdrawal on Capitec costs about 18% in fees, so take out ฿10,000 to ฿20,000 at once if you'll use it.

Flying home: leftover baht and VAT refunds

Leftover baht

There are exchange counters on the departures side of the airport, but don't count on them selling rand at a good rate. Change baht back into rand at a specialist counter in town before your last day — on 22 October 2026, SuperRich Thailand and SuperRich 1965 were selling rand at ฿2.05, and Grand SuperRich at ฿2.06. Bring your passport. Coins can't be exchanged, so spend them on a last coffee or donate them.

You can take up to ฿50,000 in baht out of Thailand without declaring it. If you'll be back within a year, keeping a few thousand baht at home for your next arrival saves you exchanging twice.

VAT refunds

Thailand refunds the 7% VAT on goods bought by tourists at shops displaying the "VAT Refund for Tourists" sign, if you spend at least ฿2,000 (including VAT) in one store on one day and take the goods out of Thailand within 60 days. Ask for the VAT refund form (P.P.10) and tax invoice when you pay.

Before check-in, show the goods, forms and receipts at the Customs inspection point. After immigration, claim at the VAT Refund office; jewellery, gold, watches, glasses and pens worth more than ฿10,000 must be hand-carried and shown again there. Refunds of up to ฿30,000 can be paid in baht cash, by bank draft or to a Visa, Mastercard or JCB credit card; above ฿30,000, only a bank draft or a card transfer is available. Fees are deducted.

If you take the refund in baht cash after immigration, you'll either need to spend it airside or change it at the departure-side counters — so a refund to a South African credit card is often more useful for larger amounts. Remember too that goods you bring home count towards your SARS duty-free allowance.

Living in Thailand and flying back and forth?

Some South African expats in Thailand fly home once or twice a year and bring rand back in their hand luggage. For spending money, that's fine. But carrying large amounts of cash through airports is risky: rand notes leaving South Africa are limited to R100,000 per person, cash above R100,000 must be declared to SARS, Thailand requires a declaration above US$20,000, insurance cash cover is limited, and cash leaves no paper trail if you later need to show where money came from — for a condo purchase, a visa deposit or a tax question.

If you're regularly moving money from South Africa to live on, there are better ways: planned transfers at good rates, within your exchange-control allowances, into a Thai account — and a clear view of how your savings and retirement income should be arranged now that your life is in Thailand.

The best cards for landing in Bangkok

With one of these, the airport ATM costs you R50–R70 plus the ฿220 machine fee — and you don't need to carry much cash from home.

Your airport money checklist

• A low-fee card — and a backup on the other network (Visa and Mastercard).
• A temporary daily limit set in your banking app before you board.
• International use and contactless switched on for the cards you're taking.
• Your passport to hand if you're exchanging cash.
• At BKK: use an ATM or go down to floor B — not the arrivals-hall booths.
• At DMK: use an ATM, or change only the fare.
• Rand notes saved for town — Bangkok's head offices pay far better.
• Some small notes for taxi tolls and tips, and VAT forms ready when you fly home.
