Very shiny and big and new - really much too big considering the number of passengers and the new terminal seems a bit of a white elephant given that they're planning a brand new airport for HCMC in the medium term. I can't say anything about arrivals but processing was pretty speedy for departures - I even got a smile and some friendly conversation from the guy at the immigration desk which are rare in the typically glum and/or stern world of Vietnamese officialdom. As other travellers have commented the duty-free and food in the airside section are pretty expensive - 3 USD for tiny little cakes at one of the cafes for instance and I paid 4 USD for a pretty but not incredibly remarkable fridge magnet. What it is really lacking is a newsagency - there's precious little to do if you have to wait there for a couple of hours (if you don't fancy paying through the nose to dine at one of the restaurants upstairs) and grabbing a decent magazine or book would be a good way to cope. At the moment all that seems to be available are the propagandist Vietnamese English-language papers - not exactly a substitute for The Economist. Overall it's hardly going to compete with KLIA Changi or Bangkok as a SE Asian hub but it's clean and efficient enough not to be the complete nightmare you might expect in a communist country.
