Hi how much is it to the airport form the city? will probably be leaving from the backpacker area
Taxi or bus?
i am travelling alone

A few weeks ago I took the airport bus #152 from the terminal at Ben Thanh market for 3000 VND (US 18 cents). The bus used to pass De Tham St., but now I am told you must go to the terminal at Ben Thanh market to catch it.
If you decide to take a taxi from the backpacker area it will cost you at least $5, and you don't really save much time by taking the taxi rather than the bus.

An off-duty employee at STA Travel (backpacker area) took me to the airport on his motorbike at 10:30 PM (2230) for 50,000 dong.
I was being sarcastic. At any rate, for 60-70,000 you could get a taxi, making luggage transport easier than on a xe om.
