My advice would be to get an AMEX Platinum Card. Not only does it offer amazing travel benefits like a $200 Airline Fee Rebate, Travel Insurance, Car Insurance, Refund Guarantee, and not to mention the free Delta SC entry with spouse and children amongst others. It's definitely worth the $450 a year, and is a must for every business traveler. You can probably make the $450 back in MR points if you spend enough. :]
