The airport offers amenities found elsewhere only in airlines’ fancy lounges for premium passengers. There are comfortable areas for sleeping or watching TV, premium bars, work desks and free Internet. A nap room is about $23 for three hours; a shower can be had for $6. If you want to put your feet in a tank with tiny fish that eat dead skin, that’s $17 for 20 minutes.
The pool is free to guests of the airport’s in-transit hotels; otherwise it’s about $11 a person. A bus tour of Singapore is offered free by the airport. The tour is arranged so that passengers don’t have to clear immigration—the airport retains passports so passengers don’t run off.

Placing rival currency-exchange booths and clothing stores side-by-side stimulates competition. Touch screens in bathrooms let travelers send text messages to supervisors when toilet paper runs out, for example.
