The water features are a nice touch

The new Terminal 3 at Changi has free wifi, comfortable chairs, natural light, blindingly quick passport control and security, and somehow manages to be an appealing place to board a plane. If the airport in Singapore can be so nice, why are some airports (I’m looking at you, Atlanta Hartsfield-Jackson, and you, Newark Liberty… and Kingsford-Smith is just as guilty) still so dingy and repellent?
