I got my Platinum card back in October.
I suppose I was lucky enough to get it with an offer for 100K points after $3K in purchases (done in a weekend trip to Chicago). I like the benefits and customer service this card offers! Way better than any Visa Signature or MC World Elite card I have.
Very jealous that you managed to get in at a time of the 100K MR points offer. Would have definitely liked to have had that. However, I'm going to offset my AF a little bit by doing the $200 airline gift card redemption, need to apply for Global Entry in order to get TSA Pre✓ anyway in order to get the credit for that, so I'll start to make it worth my while.
