I would hazard a guess that if you offered pilots the option of instructing or flying an autopilot for the same money, a lot would go for the instructing. For real flying it's hard to beat but then again you don't end up in some exotic tropical paradise (like Gatwick) at the end of the day. I personally love it and have chosen the option of going for the (albeit higher paid) instructional job over the airlines. The only downside is it's not in Scotland.
