Hey, I've been racking up points on my Citi Double Cash and I'm kind of new to this whole points game. I've heard you can transfer them to ThankYou points and then use them for flights, but I'm not sure how it works with American Airlines. Have any of you done this? Is it a good deal or am I better off just using them for cashback? I'm planning a trip to LA from NYC and trying to figure out the best way to use what I've got. I know American is part of the Oneworld alliance but not sure if that makes a difference in terms of booking with points. Any tips or advice would be awesome!
