I'm a consultant. My job causes me to travel a lot so I get a ton of frequent flyer miles. A round trip ticket to Japan from Dallas, TX costs 50,000 miles.
My trip to Tokyo only cost me and my wife 86 bucks. I have over 200,000 miles saved up. The most expensive part of our trip was the 400 bucks I paid to the kennel that babysat my two dogs.
