These airports are so clean the kids can lick the floor

Well, almost. Hey, it’s good for building their immune system right? SkyTrax has ranked the world’s cleanest airports in its annual survey of overseas travellers. 

The company also ranked the best airports in the world with Singapore’s Changi airport taking the crown for the seventh year in a row. No airport comes close to Changi, which has an outdoor pool, a butterfly garden and a sunflower garden. 

But can it take the crown for the cleanest airport in the world?
