Nopt anymore. (thankfully) For years, I never knew from one week to the next where I'd be going.
I might be taking a crane somewhere "locally", (within driving distance...up to 200-300 miles one way) or I might be getting in an airplane and flying somewhere for a couple of weeks/months to do a job.
Fortunately, it paid VERY well, and anytime I was away from home, they paid all my expenses.
I rarely flew often enough to rack up enough FF miles to actually do anything before they expired though.
