I've been in one european airport, it was pretty.
I been to Canada airport, and I would appreciate its beauty a lot better if they didn't detain me for 2 hours. I wasn't even going to Canada, I was just changing flight going to China.
Then when I got to hong Kong airport, I realize my passport is for Macau only. The security at the gate was like "I suppose to detain you, but I going to give you a chance to walk away and take a ship to Macau." I ran away so fast.
The seaport is inside the airport, but it is 15min walking distant from Canada Air luggage transfer center. I have to buy a ticket from the seaport, then take it to the luggage center to Transfer my luggage.
30 minute s later I got in a ship to Macau airport, made a stupid joke to the officer that approve my entrance (yes it was awkward).
I hate airports.
