Flying from Siem Reap to Bangkok
In short
Several airlines fly nonstop from Siem Reap–Angkor International Airport (SAI) in north-west Cambodia to Bangkok: Bangkok Airways and Emirates to Suvarnabhumi (BKK), and Thai AirAsia to Don Mueang (DMK). The 377 km flight takes about an hour. Most passengers are visitors to the Angkor temples moving on to Thailand, either to continue their holiday or to catch a long-haul flight home.
An hour's drive to the new airport east of town
The new airport opened on 16 October 2023, about 50 km east of Siem Reap town and 40 km east of Angkor Wat. The old airport near the temples no longer has passenger flights. Allow at least an hour by taxi, minibus or hotel transfer, and add a margin if you are coming straight from a sunrise visit to the temples. The terminal was built for 7 million passengers a year and is rarely crowded, but the long drive is the part to plan.
Checked bags for souvenirs and carved stone
Bangkok Airways and Emirates are full-service and include a checked bag. Thai AirAsia is low-cost and charges for checked bags, so add one when you book if you have bought souvenirs or carved stone. The flight is short enough that the arrival airport often matters more than the airline.
Suvarnabhumi rail and metro links
Suvarnabhumi is the airport for same-day long-haul connections. It sits about 25 km east of the city, and the Airport Rail Link reaches Phaya Thai in about 27 minutes, with Makkasan station connecting to the MRT Blue Line. Some departure gates are in the SAT-1 satellite building, reached by an underground train after security.
Don Mueang, north of the city, handled about 31.7 million passengers in 2025 and is the home of Thailand's low-cost airlines. International flights use Terminal 1. The SRT Dark Red Line stops at the airport and runs to Krung Thep Aphiwat Central Terminal (Bang Sue), where it meets the MRT Blue Line; bus A4 goes to Khaosan Road and Sanam Luang for 50 baht.
Thai entry rules depend on your passport, so check our Thailand visa page. Every foreign visitor completes the Thailand Digital Arrival Card within 72 hours before landing.
Continuing to Dhaka from Suvarnabhumi
The Dhaka flights on Biman, US-Bangla and Thai Airways all leave from Suvarnabhumi (see Bangkok to Dhaka flights). If you land at Don Mueang, allow time to cross the city and check in again; Airports of Thailand runs a free shuttle bus between the two airports for ticketed passengers.
No clock change is needed: Cambodia and Thailand both keep UTC+7 all year.

Frequently Asked Questions (FAQs)
Getting there
Flights land at both Bangkok airports: a few airlines at Suvarnabhumi, and Thai AirAsia at Don Mueang. Schedules change by season, so check the flights for your dates in the search above.
About 1 hour in the air. The two airports are 377 km apart in a straight line; actual times vary a little by airline, aircraft and wind.
Both. Competing airlines use Suvarnabhumi (BKK); Thai AirAsia uses Don Mueang (DMK). The airports are on opposite sides of the city, so check the code on your ticket.
Suvarnabhumi lies about 25 km east of central Bangkok. The Airport Rail Link runs to Phaya Thai in about 27 minutes and meets the BTS Skytrain there; Makkasan station connects to the MRT Blue Line. Metered taxis and Grab wait outside arrivals. Don Mueang is north of the city. The SRT Dark Red Line stops at the airport and runs to Krung Thep Aphiwat Central Terminal (Bang Sue), where it meets the MRT Blue Line; airport buses and metered taxis cover the rest of the city.
At least an hour before you would normally leave for check-in. The airport is about 50 km east of Siem Reap town, so the road trip alone takes an hour or more.
Yes. Biman, US-Bangla and Thai Airways fly Bangkok to Dhaka from Suvarnabhumi. If you land at Don Mueang, allow at least four hours to transfer by road and check in again. On separate tickets you clear Thai immigration and collect your bag, so you need a Thai visa. See Bangkok to Dhaka flights.
About 50 km. It opened on 16 October 2023 and replaced the old airport near the temples.
General
There is no time difference: both run on UTC+7 all year.
What's included
It depends on the airline. Thai AirAsia is a low-cost carrier whose basic fares include only a cabin bag, so add checked baggage when you book. The full-service airlines normally include a checked bag; the allowance is shown on your booking.
Stay & facilities
On the full-service airlines, request a Muslim (halal) meal when you book or at least 24 hours before departure through the airline's manage-booking page. On Thai AirAsia, meals are bought online or on board; check the menu for halal options.
