Airports are usually the same. At times being at different airports you might mix up the places just based on the facilities. Prague airport is similar to Frankfurt or Brusseles or even Kuala Lumpur or Beijing airport.
But Jakarta airport is special. It has not that common marble-look, the main color is brown which makes the entire building looks like wooden one. On the walls are traditional symbols and between the gates you can see nice green gardens with exotic palms.
That airport has a style. A special athmosphere which makes you feel like:..... I arrived to something very new!
