Hi,
Just to correct figatelix, as an ex ATR pilot, and ex Swiftair pilot, I can tell you for sure that you get paid also at Swiftair, as soon as you finish your type rating and you start flying, the salary was around 2500 euros/month more or less depending on your base (you get paid more money when your base is outside Spain, for exemple in Italy, Germany, France, Greece, even India or caribean!, etc..).
Maybe they have changed, it's been a long time now I left, but, I doubt.
As far as I remember the best paid ATR job in Eurpe is Air Contractor. I remember the FOs make 4000-5000 euros/month.
enjoy your flights
