I go this card two months ago and really like the fringe perks, despite the 85 fee.
I looked at all the airline cards and only Continental and Delta credit cards give you free first bag check, though this is less relavent for Southwest and JetBlue. Our family travels frequently domestically, so this pays for the fee quickly.
However, my favorite feature is the primary coverage on the auto rental insurance, which beats the heck out of reporting rental car collisions to your regular auto insurance provider. The only other card I’ve seen with that feature is the Discover Escape.
