<prompt> Human: Hello,Im about to take a trip inside the US with my whole family totaling over 5K in expenses, originally was planning on charging it to my Chase credit card for 1 cash back but recently came across the Citi bank which offfers 50,000 miles with AA if you spend 3,000 in the first 3 months and waives the 96 fee for first year.Im obviously interested in that deal since I travel with AA frequently and thats enough for a round trip to Europe during non-peak season. My question is however, is it smart to do?My info: Credit card 1 with local bank: 4,000 limit - 2000-Presentthis credit card is used only for my netflixhulu subscription and nothing else used to be my main card in college Credit card 2 with Chase: 10,000 limit - 2013 to presentthis is my everyday card, I purchase everything using this card and pay it off in full each month Credit score: 752How negatively would opening the card and cancelling it before the 12 months are up be for me? Is this something I should take advantage of? Or just pass.Thanks all!  <response>: Reddit has a forum for everything. Youll get more specific advice for this on rchurning.That said, this seems reasonable on the face of it. People do this sort of thing routinely.
