Unlike probably the majority of FTers, I built my miles and travel almost totally on leisure travel on my own dime, though I thought of trying to move into a higher travel field. Seems like most people either get way too much or very little travel in their jobs, with not much middle ground. I used to be in the "very little" category, getting maybe one domestic trip a year. The company's one-size-fits-all cost-cutting approaches applied to travel were pretty frustrating, though, especially since I did much better on costs on my own, and with fewer enforced sacrifices.

OTOH, after 12 years or so at gold or higher on nearly all leisure trips, I think it'd be hard to do it as a road warrior. *Maybe* you'll get nicer hotels, paid meals some of the time (my old company wouldn't pay for lunch), and good destinations with a chance to use vacation days to extend stays in them, but look carefully before leaping. FT has had people comparing notes about their company travel policies, and some sound pretty dreadful. And while international travelers who can get the company to pay for biz class have the world on a string with FF programs, they're far outnumbered by road warriors who either get pretty boring destinations or get the same ones again and again. It's one thing to have a job with travel but quite another to get exciting destinations or a good variety of them.
