Even though the regular offer for this card has expired as of yesterday, you can still sign up through my referral link and get the higher 60,000 mile bonus through May 16th! I know boarder42 has links to the Platinum cards as well - those have 70,000 mile bonuses (with a $195 annual fee that's not waived). Get 'em before they're gone - there's no guarantee that AmEx will offer these high sign up bonuses again, and since they are a "once in a lifetime" bonus, if you're going to get them, get the highest bonus you can!
