The travel website, The Guide to Sleeping in Airports, has named the best and worst aviation terminals in the world.

This year’s survey asked over 26,000 fliers to identify their favorite and worst terminals they have visited. The readers were asked to rate the airport’s facilities in four categories: comfort, conveniences, cleanliness and customer service.

Although no US airports appeared on the dreaded ‘worst airports’ list – none of them made it on the ‘best’ list either.

Check out the rankings below. Have you been to any of these airports? If so, share your experience with us.
