Also true to my experience.

Back two jobs ago, we had international customers with somewhat high demand to ship our people all across the world on, sometimes on a moment's notice. I had to fly out 4 or 5 times in the span of two years, but some of my colleagues could do more than that in under a year. Somehow, the flights were almost always the cheapest airline available, and the cheapest seats available. The co-workers who flew frequently, including my boss, were all using the accumulating miles to bump themselves a class up.
