Commercial airlines in India, which includes international airlines and low cost airlines among others, are passing through a third wave of expansion, according to an analytical report by Wharton School. Low cost flights, an idea which initiated large scale passenger migration from railways to airways, help Indian middle class to catch up with the fast paced world. Mergers & acquisitions in this sector are aimed at expanding the customer base. This expansion of flights in India has been inevitable given the rate at which the country is growing at present. Thanks to this, the drag of 50 or 60 hours of train journey from down south or from northeastern states will soon be a thing of the past for a large section of Indian populace.
