Well, when Air Deccan(or any other airline) says that the tickets are free - you must read the fine print below "Conditions Apply". The Conditions include that the different taxes need to be borne by the passengers. That actually brings up a price for each ticket - which is quite above that Rs. 0 really.
Although Air Deccan might not be that rosy to travel, but it still makes sense when you only consider the time and money - leaving the other luxuries behind. So what are you waiting for, go and grab the Free Air Deccan Airline tickets that are up for grabs.
