Hi!
Been commuting for 10 years now between different countries.
I live in Denmark and have been based in Spain, Germany and now London. Hard work - yes....but it is a life style choice. Do I want to spend my off days in a country where I have a few colleague friends or go home to my family. Do I want to up-root my family and limit their careers and take them away from their extended family and move them around between countries at my employers whim?? No.
It goes with the job I guess.....I know only a handfull of pilots who don't commute for the sake of their families and the few who relocated went back to their home countries within a few years.
It is not the perfect job by any means if you plan on staying home and raise a family.
