To change your Alaska Airlines flight, start by visiting the Alaska Airlines website or app, and log in to your account. Navigate to your bookings and select the flight you wish to modify. Choose the "Change Flight" option and follow the prompts to select a new date or time. Be aware that changing your flight may incur a fee, and fare differences might apply. If your ticket is refundable or eligible for change without a fee, the process will reflect this. You can also call Alaska Airlines' customer service for assistance. After making changes, you'll receive an updated confirmation email.
