The airport is located in Tan Binh district, about 8km North of the city center. It takes about 15-20 minutes to get to the center of the city from the airport.
The domestic terminal used to be the old International terminal with 62 check-in booths. It is easy to navigate your way around, especially with only 3 domestic airlines being active.
It takes approximately 10 minutes to get from one terminal to another so if you have a transit in Ho Chi Minh City, you will not be in any hassle.
Taxis line up, with proper police regulation outside of the airport. A metered taxi ride to the city cost about US$5-7 or you can asked for a fixed rate ($4-6). Airport Taxi and Saigon Taxi are among the most popular and reliable companies. It is better that you line up to get the regulated taxi than waving one off the road to avoid scams. Check with your hotel in advance to see if pick-up can be arranged.
Local bus runs every half hour between the airport and Ben Thanh market (which is a 15 minute walk from the downtown area). Buses run between 6 a.m. and 6p.m. and ticket price is 30 cents. Though inexpensive and convenient, bus is not the best option when you have a lot of luggage.
