Hi all! I have a flight tomorrow with the first leg being a flight to Seattle operated by Alaska Airlines. However, I am not able to check in for this first leg at all. The Starlux website/app said to check in directly on Alaska's website but when I entered my ticket number or confirmation number into Alaska's portal, it couldn't find my ticket.

Has this happened to anyone else? How do you navigate it? Is there a different confirmation number for the Alaska leg(s) that I missed? Please let me know! Thank you in advance!
