This thread has changed my life in a small but meaningful way. It's great to know that by applying for 3 credit cards and otherwise living my life normally , I now have 3 or 4 (or 5, maybe 6?) free roundtrips on deck whenever I need them.
I'm knocking out my AmEx spend right now and tried to use it this morning. The cashier apologetically asked if I had any other card. With a wink and a nod, I produced my CSP and it was all good. And then my cheeks jiggled as I laughed, like a bowl full of jelly.
