You say the industry has changed so much, but you joined easy in 2003 and left in 2008. What change are you talking about? It's not as if you remember flying in the 80's! Sure, things have changed. The easyJet you join now will put you on a random roster for a few years. And the pay will be somewhat less I think, and it will take a bit longer to get that permanent contract.
But once you're in, you're in. It's the same company as before, just a bit bigger and a bit more mature. Leadership is solid. People still leave now and then for BA, or Emirates or Virgin. But most stay.
So what's holding you back? If your life experience has changed the way you view the profession, then fair enough. But only you can make that evaluation. The job is basically the same.
