From the Irish Indo:
Ryanair says that its average salary is €49,992 while the average salary of Easyjet was €46,901; of Lufthansa was €41,912 and British Airways was €41,423 based on the last available annual reports.
Hmm, considering BA's starting salary is about £42k and EZY's FO salary is about £36k, this seems to be a rather creative exchange rate.
