Alaska Airlines offers a flexible flight change policy on most fares. Main and First Class tickets can generally be changed without penalty, though passengers must pay any difference in fare. Saver fares, however, are non-changeable and non-refundable except within 24 hours of booking. Same-day confirmed changes are available for a small fee, subject to seat availability. Changes can be made easily online or through the Alaska mobile app. Having such a customer-friendly policy helps passengers adjust travel when plans shift. For detailed guidance on your specific booking, call Alaska Airlines directly at 831-298-4213.
