EasyJet don't pay differently. But Portuguese tax differes a lot. As an example, as a captain in Portugal with your approx. gross monthly salary of €10,000-11,000 and you have a child. If your partner doesn't work you'll take home €600-650 more than if your partner doesn't work.
As Turkish says, first year gross is mid €140k. Assuming worst case local tax and social security you'll be looking at high 70k low 80k net. If you have children maybe add 5-10k to the net annual figure.
