The amount of cancellation fee to be charged is totally in the hands of airlines. We do not have the authority to charge cancellation fees from customers. In addition to this, providing the refund is responsibility of the airline.
In case of a no-show refund, customers must reach out to the airlines. Not many airlines will agree to provide a refund in case of a no-show. Additional charges would be deducted if you want us to cancel your tickets for you. The charges for flight cancellation would depend on the airline as well as on the departure time of the flight.
