This is an interesting piece on weather the 5 limit is gone. I have always wondered if this limit was upsetting their partners like Delta, SPG, Hilton. Because of the 5 CC cap, I don't have any of their Delta cards and was debating between getting an Ascend business or the yet to be launched SPG/MAR luxury card.
