My point is that the available slots back at 'home' were very limited. They tended to be 'booked out' early with the best times prioritised to civilian contracted flights. Being content with 'tired' mover crews simply isn't the issue - there are a limited number of teams (used to be two back in my day) which meant we couldn't come home early, and the flights were organised around such limitations.
There - I said something positive about 'those' guys
