The answer to this depends on the duration before the day of visit that you choose to cancel your ticket. If you cancel 30 days before you will get 75% of your booking amount as refund. Between 15 to 30 days of the day of visit, a cancellation will cost you 50% of your booking amount. But if you choose to cancel 15 or less days before the date of visit, you will not get any refund as the cancellation amount will be a 100%.
