I use my trusty Platnum visa...has never let me down no matter where I am traveling I hate using US carriers for airlines anyway and I don't have enough commercial national flights to put miles to use so that was never a draw for me. I have my hertz gold which covers my rental cars (and will deliver to regional airports since I primarily fly privately) and I have yet to find anyplace in the world that doesn't take visa if they take credit cards...plus as a business owner I hate amex because they charge another 2% over any other credit card company.

as for the bail out of jail thing and the emergency wire transfers...any platnum card has that feature regardless of type
