Fulminn, I love your figures based on 100 flying hours p.m, that is very realistic
I know Contract FOs who have taken home over €7000 after tax on a normal summer months. Captain's hourly rate is 50% higher. Do the maths. I suspect they're all intelligent enough to know to put money aside for the quieter months!
How can you invest any potential extra money in a serious pension plan with such a precarious job? Banks will never trust in you. Not even Bernard Madoff would have made a deal with a Ryanair slave. Those summer months incomes are just helping to cover the hard winter season, when all Ryanair Boeings are parked 24 hours a day for a few months.
Regarding those take home figures for self employed contractors, do they really pay all the taxes that they should pay, especially after 2 years? Probably not.
