Professional flying can be boring, stressful, tiring etc at times but it can also be very stimulating, challenging and rewarding. Probably true to say its not so much a job but a way of life. If you go into it for the right reasons and are the right sort of person then you will probably enjoy it.
I've been flying for thirteen years now, the last three professionally and I enjoy it as much if not more than when I started. It is true to say that commercial flying is incredibly disciplined with SOPs for everything and yes you have to fly to where you are told when you are told but this neednt be a down side to it. Its all to do with your attitude to it.
If I were to win a few million on the lottery (unlikely as I would not patronise such an institution) I'd still continue to turn up for work. I cant think of any other job where I could say that.
Why do you think Bruce Dickenson does it?
