expect about 3ooo-3800 euro net depending on personal situation(wife,kids etc) plus per diem around 1000 u$ first year fo
currently 9 off-days per 28 day roster,planning currently to maximum,expect to be away from home a lot
I really wouldn't recommend you shuttling,hard to get id-tx,bad flight schedules out of lux,you have to be 10 hrs before dep in lux,also there is a stby-system to come,often only a short rest between flights,etc.
however,for tax-reasons it doesn't matter where you live
expect around 10 years to upgrade,not much off at destinations recently,planning is really a big issue at the moment,many(incl. me)are seriously pissed off..
