Splashier airports attract aerial photographers in droves, but Singapore's Changi Airport makes no such grand architectural statement. Instead, it woos the common traveler who may be stuck here for a few hours. It is not a hermetically sealed purgatory, thanks to a straightforward design that incorporates open-air spaces, including rooftop terraces and an outdoor swimming pool. Its atrium-like terminals are lush with indoor tropical gardens that exhibit botanical thoughtfulness. Ultimately, the vines, tasteful wood trim, and warm tones help offset the coldness commonly found in international hubs. A 24-hour cinema, spa, showers, children’s play areas, and free Internet service provide the means to kill time or freshen up before the next leg of your trip.
