It is one of the best international airport in the world & very large too. I have been here few times. It is always well maintained and clean airport. The duty free shopping area is also very large. Many big brands from across the world have an outlet here. It also has many good cafes of cuisine from the different parts of the world.
One of the BEST airport experience anyone can ever have & it is just keep getting better everyday.
