Apologies if this question has been asked before. Tried searching but couldn't find anything. Asked the question in the newbie lounge but did not receive a response so I am trying again here.

I am a oneworld Sapphire member. Just wanted to check what benefits I could get on AA besides the 2 free checked bag allowance (only benefit I know). Also, does the 2 free checked bags extend to other non-Sapphire members on the same PNR?

Thanks!
