Wow, I love Bourne's response and I echo it. A couple of things I would add: I really love it when the benefits can be extended to family member, friend or companion such as waiting out a delay or layover in a club instead of a gate waiting area. Being able to come across with a ticket for someone is pretty big and the "emergency travel fund" aspect is nice insurance too. I enjoy the "game" aspect to the whole thing and plotting strategies that pay off in spades. In a couple of weeks, I will take a dirt cheap flight which will set off a chain of events that will result in about 20K. Every time I'm sitting up front on a cheap ticket with a complimentary cocktail, it's a little victory. Hey, it's just plain fun!
