The above airlines do not assign seats in advance. Please note that smarTours is not involved with your seat assignment. It is between you and the airline! However, we are suggesting that you check-in early to request for your seat(s) at the airport.


Booking your own flights has advantages like flying from your home airport, choosing your own seats, upgrading your seats, and using and collecting airline miles. Tour-only travelers are responsible for arranging their entry and exit flights, as well as their arrival and departure transfers. Unused land services including those caused by air schedule changes and delays are non-refundable and smarTours cannot be held responsible.

When booking your flights, please note that our tour starts in Ho Chi Minh City and ends in Siem Reap. We recommend that you:

  • Fly into Tan Son Nhat International Airport (SGN)
  • Fly out of Siem Reap Angkor International Airport (SAI)

Siem Reap International Airport replaced the former Siem Reap International Airport (REP) at the end of 2023. The new airport is in a different location, approximately a 1-hour drive from Siem Reap City.


In Vietnam and Cambodia, private taxis are reliable ways to get to/from the airport. You may also check the airport’s website for additional information on how to book a private transfer in advance.

The official currency in Vietnam is the Vietnamese dong (VND; ₫) and the Cambodian riel (KHR; ៛) is the official currency of Cambodia. The US dollar is Cambodia’s second currency and accepted everywhere as long as they are newer bills and in good condition. For the best exchange rates and convenience, we recommend withdrawing local currency at an ATM once you arrive in each country. ATMs are fairly common in Vietnam. In Cambodia, ATMs are less common and will dispense US dollars. When possible, choose small denominations. Credit Cards are widely accepted in Vietnam and Cambodia, but may not be accepted in smaller stores or restaurants.
