I have two of the USairways cards, both opened this year. Anniversary of first one is up and was just offered the "no fee for life" arrival card or the 2500 miles after five purchases of $50 or more. not motivated by either of those offers.
If I'm just going to keep one, I should probably keep the card that was open earlier (not that a few months makes that much difference). Is there any experience of Barclay's combining the credit lines on the two cards?
