While Alaska Airlines provides a full refund for cancellations made within 24 hours of booking, getting a refund after this period depends on your fare type. Refundable fares are eligible for a full refund even beyond the 24-hour window, as long as the cancellation occurs before the flight departs. Non-refundable fares, on the other hand, do not qualify for a cash refund after 24 hours. Instead, Alaska Airlines will issue you a travel credit for future use.
