I see a lot of ppl referring to the 2x $200 travel credit for the amex plat. How does this work? If I apply for this card in Oct will the $200 credit carry over to 2015? or do I have to use the first $200 before the new year?

Can I use this credit to pay aeroplan scam charges?

What are the best ways to utilize this 2x $200 credit?

Thanks for your time?
