American says you can bring 1 carry on....but, the overhead compartments were over filled forcing some to check their bags, because passengers were putting the personal items in the compartment. If you chose to carry a personal item you should not be allowed to put it overhead. Also, I purchased 2 tickets, and on the way we were separated by one row. The only way to guarantee you sit together is to pay for assigned seats. If you purchase 2 tickets, they should automatically be in the same row without you being forced to pay extra to be in the same row.
