Hanoi Airport

The old terminal is cramped and filthy. In the arrival the immigration is slow specially it's horribly during the mid-summer day when the hall gets sticky and hot because there is no AC! The only bathroom was one of the dirtiest one every saw among all the airports. Departure hall is a bit better but expect the slow immigration service. The new terminal was under construction at the time when I visited back two years ago which was used by domestic arrival only (funny how the planes pulled off from the boarding bridge after clearing the passengers). The new one is much better looking clean and has open-air concept which make it spacious.
