Uplinker has it right, sadly. I left the industry 2 years ago and, as much as I miss my colleagues, I do not miss the lifestyle. The industry has changed (and continues to change) and the lifestyle for pilots has gone south - as has the remuneration. A combination of advances in technology allowing for longer and longer flights and an industry now being run by HR rather than aviators means that pilots are just a finite resource to be squeezed as much as possible, for as long as possible as cheaply as possible. The real 'gotcha' though is that by the time most new pilots realise this nowadays, they are in in their early 30s, still in debt circa 100,000 euros, financially trapped in an industry that isn't what they thought it would be, are too old to start again and too in debt to be able to get married or buy a house.
If your son really wants to fly, my advice would be for him to get a good job in law or finance and to hire a Cessna at the weekends. He will have a much happier (and longer) life.
