Part of: Paying in Thailand
Which of Bangkok’s two airports you land at decides the first hour. Suvarnabhumi (BKK) is the big one: long-haul and full-service flights, one main terminal, and a train station underneath. Don Mueang (DMK) is the low-cost hub, older and smaller, with commuter trains across a footbridge. Both sit well outside the center, with traffic as the big unknown in between. The rest is choosing the ride by the clock and your bags, and getting online before the doors.
Learn the floors at Suvarnabhumi and the building explains itself. Immigration, baggage claim, customs and the arrivals hall, with its ATMs and SIM counters, are on Level 2. Taxis, buses and the rest of the ground transport are on Level 1. The train is on B1. Flights that park at SAT-1, the satellite concourse, reach the main terminal on a driverless underground people mover in about three minutes.
Getting into the city
Clear immigration, and expect the afternoon
Immigration comes first, then baggage, then customs. Lines are longest from early to late afternoon and through the November to March high season, when the wait can pass an hour. Priority lanes serve older travelers, pregnant travelers, families with very young children and wheelchair users.
Take the airport train if your bags are light
Follow the 'Train to City' signs down to B1. The line runs eight stations and ends at Phaya Thai, where you change for the BTS Sukhumvit line; change at Makkasan for the MRT Blue Line at Phetchaburi, or at Hua Mak for the Yellow monorail, about a ten-minute walk. The express has been suspended since 2014, so every train is the city line. Contactless bank cards open every gate, and tokens are still an option. In the evening rush, with a hotel near the line, it beats the road.
Or the taxi line on Level 1, and keep the slip
The official public taxis run from ticket machines on the outdoor curb between Gates 4 and 7, around the clock. There are two lines: a short-distance one for trips near the airport, and the regular one, on the meter, for the city, with the airport surcharge and any tolls paid on top. The printed slip carries the driver's and the car's details, so hold on to it until you're at the hotel. Anyone in the terminal offering a taxi outside the line is someone to walk past.
Grab from Gate 4, by PIN
Since September 2026, Grab pickups at Suvarnabhumi work by PIN. Choose 'Grab Pick-up Point' when you book and the app gives you a four-digit PIN with no driver assigned yet; walk to lanes A to D at Gate 4 on Level 1 and give it to the first waiting driver. The price shows before you book and often runs above the meter, more so in rain or at rush hour.
At Don Mueang, the Red Line across the bridge
Terminal 1 is international and Terminal 2 domestic, joined by an enclosed walkway. Don Mueang station sits across a pedestrian bridge, and the SRT Dark Red Line runs from it to Krung Thep Aphiwat, the new central station, for the MRT Blue Line; its gates take contactless bank cards. Since March 2026 taxis leave from Terminal 1, Level 1, Gate 8, and Grab from Gates 3 to 4 on the same level, or Gates 11 to 14 at Terminal 2. The A buses leave from Terminal 1, Gate 6, and the A4 to Khao San is the backpacker's answer.
Get online before the doors open
Install an eSIM at home so maps and the ride app work from the jet bridge. For a physical tourist SIM, buy it at the counter with your passport: at Suvarnabhumi, in the Level 2 arrivals hall or by the train on B1. The carriers are AIS and True, which merged with dtac in 2023.
Have the hotel’s name in Thai script or a pin on the map before you get in a car. Drivers navigate by landmark and soi number, not street address, and on Sukhumvit the soi is the address: say “Sukhumvit Soi 55” once, then “Soi 55.” Beyond the SIM, skip what’s sold in the arrivals hall.
Keep some baht for the taxi, and change only a little at the airport, where the exchange counters typically give you less than an ATM or a booth in town. For paying in town, the Yodl app asks you to verify before your first payment in Thailand. Do that in the app, then scan the PromptPay or Thai QR at the counter, and a licensed local partner pays the merchant in baht. The Thailand payment guide has the rest.
Light bags take the train. Heavy bags take the taxi line, and keep the slip.
Older guides describe a different airport: Suvarnabhumi’s East Expansion slipped to 2027 or 2028, the express train hasn’t run since 2014, and Don Mueang moved its pickup points in March 2026. Trust the signs on the day. In the rainy season, storms arrive in the afternoon and evening, and a landing in a downpour means busy, pricier ride apps.
Mistakes to avoid
Taking a ride from anyone outside the line
The official taxis run from the ticket machines on Level 1, and Grab from its PIN lanes at Gate 4. A stranger in the terminal offering a car is neither. Walk past and join the line.
Throwing away the taxi slip
The printed slip is the record of which driver and which car took you. If anything goes wrong on the way, it's what identifies them. Keep it until the bags are out of the trunk.
Giving the driver a street address
Bangkok drivers work from landmarks and soi numbers. Show a map pin or the hotel's name in Thai script, and on Sukhumvit lead with the soi.
Booking something for the afternoon you land
Immigration is slowest from early to late afternoon and through the high season, and the road in is at the mercy of traffic and rain. Book nothing on day one that a long line could break.
Common questions
How many airports does Bangkok have?
Two. Suvarnabhumi (BKK) takes the long-haul and full-service flights and has the airport train in its basement. Don Mueang (DMK) is the low-cost hub, home to Thai AirAsia, Nok Air and Thai Lion Air, with commuter trains across a footbridge. A shuttle bus links the two for connecting passengers, from BKK Level 2, Gate 3 and DMK Terminal 1, first floor, Gate 6; check that your ticket qualifies, and allow one to two hours in traffic.
Should I take the train or a taxi from Suvarnabhumi?
The train if your bags are light and your hotel is near Phaya Thai, Makkasan or a BTS station, especially in the evening rush. The official taxi line on Level 1 if you're carrying a lot or going where the train doesn't. Grab for door to door, at a price that often runs above the meter.
What does the taxi into town cost?
The meter, plus an airport surcharge and any expressway tolls, which the passenger pays on top; luggage and slow traffic can add more. Grab shows its price before you book, and that price climbs in rain and at rush hour. Both move too often for a figure here to stay true.
Should I get a SIM at the airport?
Install an eSIM before you fly, or buy a tourist SIM at the counter with your passport: at Suvarnabhumi, in the Level 2 arrivals hall or by the train on B1. The carriers are AIS and True, which merged with dtac in 2023, and AIS sells most of its tourist packages as eSIMs too.
When is the best time to come?
Mid-October to mid-February is the cool season and the best weather, and the high season, roughly November to March, means the longest immigration lines. January and February bring haze, so check Air4Thai or IQAir. Mid-February to mid-May is hot, April hottest, with Songkran, the New Year water festival, in mid-April. Mid-May to mid-October is the rainy season, with heavy afternoon storms and September the wettest month.
