Mods, if there's a thread that these questions apply to please move, I've searched but can't find what I'm looking for.

Situation: I have a group of clients (18pax) arriving on an AA flt from PHX to SFO this Sunday. It's a US A321 and for the last week it's been arriving in Terminal 1 (usually Gate 45)

Question 1: Does anyone know if the bags arrive in Terminal 1 or Terminal 2? I'm asking because I have a motorcoach staging in the Courtyard to pick them all up (there will be a 2nd staff person meeting everyone in baggage claim) and I'd love to know in advance where to have the staff and the coach positioned.

Question 2: They all leave 3 days later back to PHX (which has also been departing from Terminal 1) and I'm curious if they need to check-in at Terminal 2 and then walk to Terminal 1, or if there is still check-in/ticketing for this flight at Terminal 1.

Thank you in advance for your help, I really appreciate any insight you might be able to provide.
