There's a suggested limit of 2 cards per AoR, but from what I gather, you are only limited by your credit and income. You can always move around credit to open a new card if you have enough.

As far as using them both to travel, you can do one way tickets, one on UA, one on AA, that's what I'm planning on doing.
