I've been reading up on the AA lounge rules for a July flight from SFO to JFK (flight 12) so I needed to check my class of ticket (Z class). I noticed that my seats which I chose when I booked in December have been changed to "unassigned" and I cannot choose new ones as they are all showing up as unavailable. After doing some research here, I think this happened after a slight schedule change. I'm nervous that I won't be able to check in online.

Also, should I be preparing myself for a bump down to business class? We have no status at all and we are flying on an Alaska Airlines partner award. Kind of bummed as we are not business travelers and we were really looking forward to flying first class.
