The first thing you should do after realising your reservation error for your flight ticket is to make the necessary corrections. You have the option to cancel your flight if a correction is not feasible. This airline is aware that occasionally a passenger  incorrectly purchased ticket needs to be cancelled. As a result, Singapore Airlines Flight Change Policy is put into place to give passengers the easiest way to cancel their tickets. It makes it easier for guests to cancel their reservations whenever they choose. They can also find out more about the prerequisites, restrictions, and fines associated with cancelling this policy.
