Trancada, with all the extra’s and per diems you roughly earn nett what you earn gross in the first year. You might work the ocassional extra day but bear in mind that you do not have many days at home as it is. Especially if you bring your family over you might treasure your time at home more than a few extra euro’s. Believe me, crewcontrol will use you to the max anyway! Expect many changes and massive delays! If I were you I would wait until the CWA negotiations have ended.
Whatever kind of experience you have, as long as you fulfill min req’s you should get an invite. Many guys here with only Airbus experience.
I do not believe they fail people on purpose. You receive a package from CLX to prepare mollymawk. No need to fork out hundreds of euro’s. The selection is tough but doable.
