<prompt> Human: I just recieved my 3rd credit card. Below is the summary of each card:- CC1: 7 years with 5k limit w cashback. - CC2: 2 years with 750 limit.- CC3: 1 month with 7k limit w cashback.No balance on any of the cards.I travel for work a lot both abroad and domestic and CC1 isnt accepted generally outside of the US I front travel cost and then get reimbursed; does not include flights. I got CC2 for international travel thinking that after the intro period I could up the limit, but every time I call they will not increase the limit bc of the type of card. Anyway I applied for CC3and got approved and it is accpeted world wide. Question is should I cancel CC2 or just let it sit. From what I see canceling CC2 would increase my average age of accounts since CC2 and CC3 are so recent compared to CC1 and it would only decrease my availiable credit slightly. Does this make sense?  <response>: No annualservice fees? Leave CC2 open.Since you travel so much for work or whatever, and CC1 isnt accepted most places, last thing you want is to have CC3 suddenly get flagged cancelled while out of the country... and NOT have a backup until you get CC3 sorted out.
