Yes, go places now before the big commitments come around. I travel 5 months of the year around the world by myself, and spend about 15-20k a year doing it. 35-40% of this amount is for tickets. This year I will fly 180k miles or so, about 140k of it paid. If you are at the highest level earning, you can earn two RTW trips a year in coach, or about 1 1/2 in Biz if you pick the right carrier.

If you pay *close* attention to the Mileage Run forum, you will see numerous good deals every year. Just in the last year, I've booked 17 tickets to mostly international destinations. Normal price for these tickets would be about $25,000. Flyertalk price = Less than $5,000.
