Domestic passenger demands of Asian countries are very much lower. Especially in countries such as China and India, majority of the passengers are domestic. Please please please increase the domestic passenger demand. It is pity to see an airport with below 20 million pax at extreme, which is actually more than 40 Million.
Chinese Airports includes Chengdu, Kunming, Shenzhen and Indian Airports such as Delhi, Mumbai. Also many airports from China and India has more than 15 million passenger transported within an year.
Please consider the original statistics also from ICAO\IATA.
Please do favourable for this
