Hong Kong International Airport
When you come to Hong Kong by air, you will arrive at the Hong Kong International Airport, the 2nd biggest airport in the world. There are two terminals: Terminal 1 and 2. Terminal 2 is just for checking in so if you are checking in at Terminal 2, you still need to ride the transit system to board the plane at Terminal 1. In my experience, you need to arrive at the airport 3 hours before the takeoff. But luckily, the customs are fast. Mostly you just need to wait for 5-10 minutes.
