Tan Son Nhat International Airport (airport code SGN) in
When stepping off the airplane, prepare yourself to be welcomed my a warm hug of sultry heat waves! Vietnam was one of the most humid and just downright hottest countries I have visited. Locals seem to relax during the day and sit on the street chatting, while selling all sorts of foods. Then at night, they head to the market and out on the town. Don't forget to drink lots of (bottled) water!
The easiest and least expensive method of transport from the airport to the city is the relatively recently introduced bus No. 152. It's air-conditioned, and will drop you off in the city center.
However, we didn't exactly know about this at the time and first agreed to take one carrier's transport service, until we found out that it was no more than a moped. But he was convinced he could squeeze us and our luggage on the tiny bike. Rather than finding out, we played it safe and took a tuk-tuk.
When heading home, don't forget that you will be asked to pay a departure tax as you're leaving the country (unless it was included in the price of your ticket) - don't spend all your money before you get to the airport! I believe this is under $20.
