I recently visited Mumbai airport that was first experience on Mumbai airport . It’s too large and clean but so much rush especially on domestic area . Easy way to find your flight direction are given to every where. You need not to go outside for food or shopping everything is present their and easily available . Just becoz of slient airport no announcment for flight you can see on board every time mentioned on that. Security is very good and strict and helpful in nature . Buses are present to drop near the flight . After exist from airport lots of taxi and online cab and their store are present
