Morally, it sucks, but financially, you need that airplane at 85-95% full to generate a profit from a class I took in college. So they take the numbers game and try to maximize the load-out on average no-shows. Honestly I don't blame them for doing it, but on the same token, hope I never get bumped if I "have" to be there. Then again, I'd probably fly myself if that were the issue.(boss let's us use the planes for a very reasonable rate)
