At the time of booking, the airline must clearly "indicate" the amount of refund money that will be given to passenger in case of cancellation, the charter states.
Civil Aviation Minister Suresh Prabhu released the passenger charter Wednesday which specifies rights of air travellers.
The charter states that if a domestic flight is expected to be delayed by more than six hours, then the airline would offer an option of "alternate flight" to the passenger within that time, or it will refund the full price of the ticket.
It also said that if a passenger is informed of flight cancellation less than two weeks before departure, the airline must offer an alternate flight to passenger or refund the ticket completely.
At the time of booking, the airline must clearly "indicate" the amount of refund money that will be given to passenger in case of cancellation, the charter states.
If any passenger is denied boarding due to over booking of a flight, the passenger would not be liable to hold airline for compensation if he or she is given an alternate flight within one hour of original flight's departure, it states.
