Airports are one of my least favourite places on earth. Whoever believes “Getting there is half the fun” has not spent 14 hours crammed into economy class, followed by more hours wandering in a bleary daze around an airport while waiting for another bout of economy purgatory on a connecting flight. So it’s a pleasant surprise to encounter something that gives a humanising touch to otherwise soulless international mega-airports. The butterfly enclosure at Singapore’s Changi airport is one such delight, as is the artwork installed at San Francisco airport. I love the wit and whimsy of this saxophone wall installation.
