I live in capital of india that is delhi . being a business man I have to travel different parts of the country for the earnings. DEL airport is among the best in cleanliness and among the security purposes . I still remember the first day I went to airport when I didnt even knew where to and how to take boarding pass. employes at airport are very responsible and supportive. they helped me at each phase to finally board my flight on time and with ease. I would recommend all of you to make visit the airport of delhi atleast once and inspire to clean india.
