24-hour risk-free cancellation: You can cancel for a full refund within 24 hours of booking, as long as the flight was booked at least 7 days before departure.
Basic Economy tickets are generally non-refundable and non-changeable unless within the 24-hour window.
If you cancel after 24 hours, most non-refundable tickets will give you a travel credit instead of a refund.
