In the absence of any clear explanation into why AA is terminating accounts (it could be just because a rogue AA employee doesn't like people born in July, we simply don't know), there is only one class:

"People who had their accounts terminated and any associated flights cancelled with a simple boilerplate email claiming expoitative practices, and no explanation or communication otherwise when pressed for further information".

Maybe later during discovery AA can help us slice and dice the class, but till that happens this is a very simple class of people who have been unjustly terminated and thousands of dollars worth of miles confiscated. It would be very similar to if e.g. Amazon or Uber or any other company did unexplained account terminations while those accounts had balances of "UberCash" or "AmazonCredit" etc worth thousands of dollars.

We can start with that class and if/when AA admits that this is related to Citibank, we can drag Citibank into the lawsuit since it looks like AA & Citi conspired to have a scheme where one corporation will issue the miles (after doing a full credit and background check against one's ssn, so these are legally gotten miles), while the other corporation will mark those miles as fraudulent to terminate accounts. If AA ever names Citi, then they are admitting to a criminal conspiracy here to defraud users by deciding the miles they sold Citi were ineligible if Citi ever issued them to their most loyal and frequent customers.
