Following, the language certainly implies Alaska will not only through check but waive the domestic baggage fee on seperate tickets to a international partner? Main concern is that your connection is under 12 hrs not over.
Seems to good to be true as an American Airlines flyer where they won't even disscuss through checking bags on seperate tickets no matter how much you pay them.
Travel that includes multiple airlines or ticketsIf your travel includes multiple tickets, and/or travel on more than one airline, your baggage fees and rules may be determined by the other airline. Please check your ticket, or call Alaska Airlines Reservations at 1-800-252-7522 to help determine which airline rules and fees apply to your journey. When making international connections on a separate ticket to other airlines within twelve (12) hours of arriving in the connection city, you may follow the baggage allowance and weight restrictions of the international airline - provided a ticketing and baggage agreement is in place between Alaska Airlines and the other carrier.
