Hi all,

Apologies if this is in the wrong forum... couldn't figure out a better place!

So I currently hold the US Airways Barclaycard Mastercard and am quite happy with it. I am planning to redeem my miles for a roundtrip to the Caribbean next October. As of now, I have just under 75,000 miles and will likely have just shy of 85,000 by the time I book (likely in March or April).

I am considering picking up the AA Citi credit card and getting the 50,000 bonus after 3 months / $3k in spending. With all that in mind, here are my questions...

1. What is going to happen to my US Airways Mastercard once the programs merge? Will it get converted to a Citi AAdvantage card?
2. If I wait until I get the additional 50,000 miles AND for the programs to combine, I should be able to get first class roundtrip tickets (looks like for first class, it's 30k per ticket, so with 135k miles, that should cover two first class roundtrips). Is there much risk to that strategy? Namely, is it likely that award trips will be all but gone by the time those miles get credited to me?
3. Ultimately, do you think it's worthwhile to apply for the Citi AAdvantage card? I will probably take advantage of the first year without a fee and then cancel.

Thanks!
