Ok here is the deal mate,
the starting salary will be the same except for inflation correction. Basically they reward you for coming to Netjets with a very nice paycheck at the start (concidering that you pay only 25% tax in total) and you can increase that by 10000 euros, but thatīs it for the moment. Maybe in the future there will be more money.
In all fareness, I could be in the flagcarrier of my country for 20 years and have attained the position of captain 747 and I would still not get the same net salary as here in Netjets.... But then again tax in my country is normally 52%......
