Hi,

After AA and US merger, can I use these passes in AA Admiral lounges?

Also I know one does not need to present the paper pass to access the lounge and only needs to let staff know the dividend miles number. I have multiple US mastercards and so I received multiple welcome letters with the pass. I wonder if i have multiple pass "credits" stored in my account? Can anyone please advise how it works (especially after the merger)?

Thanks.
