thats more or less the case. Mind you that over the amount of € you earn under 42000 you pay 25-33-42% tax (different scales) so FO who earns 3300 takes home ~2250. Capt. max. brut. ~€163.000; variable depending on profit-share.
Another thing is study debt. This is deductable from your tax in Holland. So a new FO with study debt takes home his brut. salary. Furthermore, Transavia pays TR.
