Hello. I am new here. I just started in the CC mileage game. I just met my 50k on my Chase Sapphire reserve and am receiving the IHG rewards Club Premier in a the mail in the next few days. My question is what my next step should be.
Do I continue with Chase cards until I've met the 5/24 rule? I am at 3 cc's in the last 6 months (I got a BJ's cc about 6 months ago). I have an Alaska air which I use pretty much only for the companion fare.
But i'm thinking of perhaps getting a JetBlue card. Or maybe the Chase Freedom? I just logged into Card Match and saw that I was pre-approved for an AMEX Platinum with a 100k bonus if I spend 5k in the first 3 months. which I understand is a good deal.

Do I only get chase cards until the 5/24 rule is met? Or do I get the AMEX and take advantage of the great deal (even though I already am paying $450/yr for my CSR?

Am I risking losing the AMEX offer if I don't take it now?

thanks in advance.
Dave
