Tan Son Nhat (Tân Sơn Nhất) (IATA: SGN | ICAO: VVTS) is Vietnam's largest international airport. There are two terminals: the shiny, pleasant international terminal which took over all international flights from 2007, and the old but functional domestic terminal 200 meters away. The airport is conveniently located about eight kilometers from the heart of the city. The international terminal used to offer duty free shopping after you landed, but that ended in early 2010 – purchase such items at the airport from which you are departing to visit Vietnam. Both terminals have limited food offerings at high prices once you pass immigration on your outbound journey.
Immigration and customs; changing currency
Immigration protocols at the airport are very streamlined. As of August 2012, it is no longer necessary for most passengers to fill in any immigration or customs declaration cards. (The latter may be necessary if you are intending to stay in Vietnam for a long period, or carrying unusual goods.) The baggage carousels are one level down from the immigration booths. You will need to have your checked-in and hand-carry luggage X-Rayed before you leave the restricted area.
After you clear customs, you will find currency exchange booths to your right. The currency of Vietnam is the Dong. Currency exchange rates at the airport are competitive, and it is preferable to change money here than at the backpackers area in the city which tends to have less favorable touristy rates. Ask first if there's a commission fee, because this will add to the cost of changing money and remove any rate advantage that is offered. There is an ATM machine on the right side near the currency exchange booths, which you can use to withdraw cash if you have an appropriate bank card. The withdrawal fee is 20,000 dong.
