I fly primarily for work. I teach / proctor doctors in the use of a new and somewhat complex surgical product. Half of my flights are to Europe and the other half are to South America.
Since I started traveling for work I have been doing more leisure flying as well. Last year I flew to SLC for a ski trip, DC to visit family and see the sights with the wife, and Chicago for a combo work / fun trip. Next year I'm going to fly somewhere exotic and interesting with my wife. I just have to convince here that it will be more fun than doing a basic Europe trip with her. The plan is to use at least half of the points I have accrued in the last 18 months.
