Arriving in Ho Chi Minh Airport is not a problem but getting to the city center is sometimes a problem especially arriving at night. Your only option of public transportation is taxi during night time. For your own security and safety take the taxi if you have a very late arrival
If you arrived in daytime the cheapest way to reach the center is the "white/blue" bus. Less than one dollar you reach the city of Saigon. We staying at the tourist area district 1 Pham Ngu Lao Street. The bus don't go that far, but you can ask the driver to stop closer to that area so you have less walk to do
Ignore the taxis, unless you have dozens of luggage or you have money to burned. Or maybe you want a comfort ride then go ahead take the taxi. Taxi is indeed comfy! if you are lucky to have an honest driver
Taxi cost us more than 300,000 dong from the city center to the airport, as we have no time catching bus going back to the airport
The bus No. 152 air-conditioned airport bus is the cheapest way to the city from the airport. For 6,000 dong per person plus a 4,000 dong fee for bags which varies randomly, the bus will drop you off at the east end of the Pham Ngu Lao area, or at the bus terminal on the south side of the Ben Thanh Market roundabout.
Upon exiting the international airport terminal, turn right and you should see the bus waiting on the road opposite Burger King. There is no sign indicating where the bus stop is, but if you ask a uniformed taxi warden he or she will point it out to you. If not, walk down to the domestic terminal, which is about a three-minute walk away. Try to have exact change or you will be given coins in return.
Note: Ignore taxi drivers that may tell you there are no more airport buses. However, the bus is only available until 6pm.
The fee for bags range from an additional 4,000 dong for a smaller bag to 14,000 for two large bags. Try to have exact change or you will be given coins in return these are legal tender in Vietnam, but many places do not accept them.
Hope this will help some expats.
