I'm yet to find a definitive answer.
There isn't a definitive answer. The salary can hugely depend on your marital status, number of children, centre of economic interest, time spent in the company which increase loyalty bonus, and the level of performance bonus in a given year.
I'd recommend contacting a local accountant with your personal details and the gross expected salary. I believe the company are reluctant to quote net figures as it is a complicated subject. Many of the pilots have used Van Doorn in Lisbon and they are very familiar with all the issues, numbers, charge sensible money and speak english. You'll find them on Google. They can offer good advice.
As an aside, the gross figures quoted have been understated this year in my experience, i.e the actual amounts earned have been higher than advertised. With various bonus granted (including loyalty for those around more than two years) the Captains have been grossing in the mid €140Ks.
