Here's the thread where I applied for Platinum back in late March. I know for a fact it was April 2012 when I signed up for the PRG. So 13 months would mean I wouldn't have been eligible to upgrade until May or maybe June...
I have only called Platinum Concierge twice so far. Once was to set up our Europe trip later this month, and the other was to enroll in the Starwood Preferred Gold program. Both times have been American CS, and both experiences have been much, much better than what I received when I had my PRG. I can confirm that the reps for Platinum are significantly more experienced, they have been able to answer any questions I have immediately and with clarity.
That's good to know. That's really the one thing I wish about Amex - that they would bring the CSR jobs back home. I would be willing to pay higher annual fees for that. And it would really show that they want to stay on top.
So, I didn't know you could actually do that. Not sure I'd get the full benefits of the card, but if the CS is all American based, I would give that serious consideration.
