Singapore seems to be pretty good at planning things, whether it's lots of greenery along roads or lots of trees in parks. The Changi Airport is no exception. Even though the airport is busy and has a lot of shops, restaurants (quite a few are Halal), and such, it doesn't have a harried antiseptic stressed feel. It's rather comfortable, truth be told.
The airport even has a small sort of park which we rather enjoyed, as did other people. 🙂 Fish in the pond, blooming flowers, a few palm trees… 🙂
