Nice airport, easy to use however expect to get jacked around by Customs agents. They are totally corrupt and do not be surprised to have to pay a bribe for some imagined infraction. They are highly negotiable and if you have the nerve to call their bluff you will win. This has happened to me at least 3 times.
The VISA on arrival system is very good and in general this is a very nice airport.
Also the taxis in the cab stands have "fast" meters. There are only a couple of companies that are "straight" such as Vinasun but they are not at this cabstand. If you are staying in D1 do not pay more than 150,000VND ($7,50). Anymore and you are being ripped off. I typically tell the cabbie what I will pay. They will argue until you threaten to get out. Then they will laugh and you are on your way.
REASONABLE AIRPORT GOOD INTERNET GOOD FLIGHT FROM MELBOURNE
I love Saigon Airport
Taxi drivers cheating - expensive airport (international) - immigration good/almost no waiting - sometimes security rude - close to city center
With the opening of the new terminal, SGN has really improved to an airport that is spacious, efficient, and offers a generally excellent experience. It's lack of a market-type atmosphere, cluttered with shops, is a relief after places like Changi and Hong Kong.
