The Ministry of Civil Aviation, India released a charter regarding the rights of domestic air passengers
• First, make sure to check the cancellation charges, ticket amount break-up and refund policy when you’re booking a ticket. If you cancel your ticket, your airline has to refund all the money that came under statutory taxes, user and airport development fees and the passenger service fee. This applies to all types of fares, including promos, special fares and where the basic fare in non-refundable. You can choose to hold the refund amount in a credit shell by the airline, but it is not the default practice of the airline.
• Know that you are not liable to pay any additional refund-processing charges, and if the carrier is a foreign one operating to/from India, the refund will be processed as per the rules of its country of origin.
• At least one integrated display should be provided that includes the schedules, fares, rules and seat availability of all participating carriers. Also, if you point out a legitimate correction of your name within 24 hours of booking, the airline cannot levy any additional charge to make the change.
• You can cancel or amend your ticket without any additional charge within 24 hours of booking it. This is possible up to 7 days before the specified flight departure’s first leg.
