Sorry if this is posted in the wrong place.

I'm not a churner nor an AOR-er.

I applied for the US Airways Barclays card in January and would like to take advantage of some large, upcoming purchases by applying for the Citi AA-50K card, about 45 days after the US Airways application.

I think most sources suggest waiting at least 91 days between new applications, to lessen the hit of new credit card inquiries. However, if I can't wait 91 days, then a) how much of a hit will I sustain at the 45 day mark, and b) how long will it take to recover from that hit?

Thanks!
