Singapore Changi Airport

Consistently rated the world's best airport — as much a destination as a transit point, with four terminals plus the Jewel complex.

Terminals 1–4 are linked by the free Skytrain; Jewel (home of the Rain Vortex waterfall) connects to Terminal 1. Terminals are spread out — check yours before you arrive.

Numerous paid and airline lounges, plus free perks: gardens, a butterfly garden, movie theatres, and even a rooftop pool.

The MRT reaches the city in ~30 minutes; taxis take about 20 minutes to Marina Bay.
