2. and 3. I actually don't know the current answer to these questions. I believe reports have varied since AS and AA weakened ties, but perhaps someone else with more recent experience can chime in.

4. Everything at SEA is connected behind security. You may need to switch concourses, which could involve some walking and perhaps a brief train ride, but you shouldn't need to re-clear security.

5. Recommend that you obtain the AS confirmation code and ensure that the AS side of the reservation has your trusted traveler number attached. If not, simply add it yourself on alaskaair.com. I'd recommend just getting boarding passes from AS for your AS flights. And, no, an AS frequent flyer membership is not required.

6. Yes. There's no lounge at FAI, but you can certainly access any of the three AS lounges (C, D, and N gates) as an AC member at SEA when you are flying either AA or AS.
