I love my Amex Gold Card, been thinking about upgrading it to the Premier Rewards Gold card, the yearly fee on the Platinum card is just a little more than what I'm willing to pay right now compared to how much I use it.

I'm dropping AAA because it comes with Amex Roadside assistance which gives me more free miles than AAA, so that by itself is worth it. Then there's rental car insurance, baggage insurance, travel agents, list goes on and on.
