https://community.expensify.com/discussion/38760/ethiopian-airlines-cancellation-policy-cancel-flight-tickles-change-flight-date-name-of-ethiopian/ TheEthiopian Airlines Cancellation Policy provides flexibility and convenience for travelers. You can cancel your flight free of charge within 24 hours of booking and receive a full refund for any ticket purchased at least 7 days before departure. However, if you don’t cancel within this window or fail to show up for your flight, no refund will be provided to you. Outside of the free 24-hour cancellation window, all fares are non-refundable unless your flight is cancelled or delayed by more than 4 hours due to reasons within the airline’s control, or due to serious illness or bereavement.
