Somewhere between half and three-quarters of my air travel is for work. I'm on a sales team, so I travel to meet with prospects and customers, and to support my company at industry events like trade shows. The rest is leisure travel, which I engage in because I enjoy visiting friends and relatives far away, seeing natural beauty, and experiencing different cultures.

Often people say that traveling frequently for work makes one less inclined to travel in his free time. Burnout, etc. That's true at the extremes, but I am in a position where I find the opposite to be true (as one or two others in this thread have also noted): Traveling frequently for work has made me more likely to fly for leisure trips.

I figure there are two reasons for this. One, regular business travel normalizes the process of flying. I'm quite adept making reservations, packing, and navigating airports and ground transport-- things that flummox a lot of other people. Two, my business travel helps me accumulate points and status that make my leisure travel less expensive and more comfortable.
