The salary is above the standard german salary, companys like Air Berlin, LTU, Eurowings etc pay a lot less than that and LH does not pay much more.
It has to be above loco-standard - for known reasons, I think we all agree on that.
Of course some companies pay less, in Germany or elsewhere, but so what? We're living in a globalized world, we fly international routes, and therefore compare the salary against other international companies.
If somebody wants to return to Germany, he'll make some compromises on the terms and conditions. Depending on how homesick you are, or whatever your reasons may be.
But it's a pilots' market we're in right now. If you go there type-rated and experienced, then obviously you compare this offer to similar offers from other companies elsewhere.
