Yes, Alaska Airlines allows flight changes—call 1-808-865-4414 for guidance tailored to your booking. Most Alaska tickets allow changes without a change fee, except Saver fares, which are non-changeable. You can modify flights online under “Manage Reservation,” through the app, or by contacting customer service. If your new flight is more expensive, you'll need to pay the fare difference. Some discounted fares may have additional rules. Making changes as early as possible provides the most flexibility. Alaska also allows same-day changes for a fee if you want to switch to a later or earlier flight.
