Somehow I dont see you using anything but Monopoly money...

I am glad I have never had to deal with this...It is nice working for a company that covers over 90% of my travel expenses....

platinum american express all the way.

the card allows you access to airport clubs.
they stand behind you on any dispute.
good points program.
first access to events (concerts and other crap).
some restaurants have reserved tables for platinum or higher amex members.

American Express is THE BEST Credit card company out there, IMHO.. My wife and I spend around $3k/month on our Amex, and of course, pay it in full every month. They are very easy to deal with, and customer care seems to be very helpful with any questions you may have.
