We will be transiting from Terminal 1 (Cathay arrival) to Terminal 2 (Starlux departure) at TPE for our TPE-LAX flight.
1) Do you know if we can check-in online (booked as AS Award flight) with Starlux 24 hours prior to departure and obtain a mobile boarding pass?
2) If #1 does not work, will they allow us to obtain our boarding pass at transit counter instead?
Hopefully, you or someone has some first hand experience.

I understand this will not work if we have checked baggage. Hopefully, we can just pack with carryon.
