One of the best airport in the world in form of location, facilities, design place number of flights. Proud to be Indian. Security and attention of the official really appreciable. Service providing staffs are very good by nature. Easily anyone can go from one to another terminal. Well maintained and clean compound and had the stores of most of the popular brands. Washrooms are very clean. Terminal 3 is so beautiful and lots of parking space available here. Food is easily available here but at high cost. Overall happy with airport service.
