Hello @DennisNguyen ,
I think Singapore’s Changi Airport is well known as one of the best airport. Once I had more than 4 hours lay over and you can always find fun things to do. The best part from the airport for me is the variation of restaurants they have, since I am a foodie.
What is your favorite part of the airport?
In addition to that I am changing your topic label to Travel, so it will get a better attention.
