Just applied for the Amtrak Guest Rewards Platinum MasterCard almost certainly expecting a denial. Lo & behold got an approval with a 5K limit. And I believe that my credit score is a bit mediocre at the moment (used to be higher pre-recession, then I recovered a bit, but I'm still working my way back to where I was). I'm truly shocked. Glad we're getting on this before the feds decide to raise the interest rate and/or we fall into another recession! This will certainly help me out in my continued travels via Amtrak. Since I'm not located in the NEC and only visit there occasionally, I did not think the World MasterCard along with its annual $79 fee was worth it for me.
As for the Chase card, I'm not sure what exactly I'm going to do with it just yet. I kinda wish I could convert it into a Sapphire card instead of a Freedom card. But Freedom's an okay card, not the worst, but certainly not that useful for travel. Like others said, you can get some decent cash back during their category promo's.
