It's all impossible to say. No one has a crystal ball, and no one can give you the answer you want. You just have to decide if you want to live your life wondering if you should have done it or not. If you do it, buckle up, it can be a long, challenging road.
I'm 40, have worked at six airlines, been through two furloughs (anticipating a third), one downgrade, one bankruptcy, and one company that doesn't exist anymore. Still nothing else I'd really rather do though.
