What are some unique airports in the world?

KANSAI INTERNATIONAL AIRPORT

Kansai International Airport Osaka, Japan

Kathamnadu - very small and not properly equiped, reminds the train station instead, Johanesburg - playing great music, Paris- with a smell of cheese, Dubai and Bankok - great for shopping; Ibiza , Maldyves, Seychelles - in front of the sea. 

I think the most unique airport in the world is Princess Juliana Airport at Caribbean archipelago...

But as regards to shine and glamour Ataturk is maybe the best...

By the word "unique" I take it as a positive term and not to associate it with the danger or negative aspect of its effects on either flying or traveling. Some of the unique airports, in this case, are Changi in Singapore, Dubai of course, Schiphol in Amsterdam and Kai Tak in Hongkong which are all impressive in their structure and amenities. I heard of some others but these are the ones I am familiar with,
