A man looks at a koi fish pond at Singapore's Changi Airport. The airport, with its gardens, public art, business centres, and retail and dining, was voted in 2018 the world's best for the sixth consecutive year by Skytrax. Sixty-six million passengers moved through the airport in 2018, up from 62 million the previous year. Changi is building a ten-storey retail and attraction centre topped by Canopy Park, complete with a hedge maze and bouncing nets. Skytrax was expected to unveil its 2019 airport rankings in late March, making it unclear at the time of this writing whether Changi retained the top ranking.
