I knew airports were becoming more posh, but installing a giant 40-foot-tall slide takes it to another level. Just pay $16 and you'll be able to have two gos at swooshing down the slide at an alarming 19 feet per second. Apparently Singapore's Changi Airport also has a butterfly garden, a movie theater, and a Balinese-themed swimming pool. They'll make the airport so good, you won't ever want to leave.
What's the most over-the-top thing you've seen in an airport?
