If your plans change shortly after booking, you may ask, How Do You Cancel A Qantas Airways Flight? within 24 hours? Qantas offers a flexible cancellation window that allows travelers to cancel flights within 24 hours of purchase without penalty, provided the booking was made at least seven days before departure. Cancellations can be done easily through the Qantas website, mobile app, or by calling customer support. Refunds are typically processed to the original payment method. This policy helps passengers book with confidence, knowing they have a grace period to adjust or cancel their Qantas flight stress-free.
