This isn't set on a specific FF program, but you could try going for the AmEx Platinum card here:
http://thepointsguy.com/2011/04/maxi...m-card-review/ It has an annual fee of $450, but there are a TON of benefits that would help with kind of travel... 25k points after spending $2k over three months, which can be used to redeem vacations with agencies like Travelocity (and when you "pay with points" AmEx deposits 25% of the points you use BACK into your account); $200 annual credit for airline fees (checked bags, in-flight meals, etc); access to 600+ lounges around the world; int'l business/first class companion fare (expensive to buy the first ticket, but if you want to splurge); along with many other travel benefits and memberships. Worth a look...
