Well - I have given my interest for Etihad - just in case... I am though almost 100% sure I will not take it. Showing interest is quite far from "wanting to leave"...!
And to the future; Neither me nor you know what it will bring, and I have no idea where you get the 10-20 years from. It may as well be Norwegian og Air Berlin that goes belly up. Everyone should do what they feel is right for them. In 30 years or so they will know if it was a smart move...
