I agree with above posts - VAA is not the place to be in a recession/depression. I say bid a Northern base @ Easy or hold out for BA. Even with the BMI uncertainties, BA still represents one of the few long-term viable options and the flying/fleet mix is varied. Sure, you will be an FO for the next 20 years at least, but you will be an FO on the 787/777/A380 for a decent chunk of those years if you wish. This career is a gamble and you can only decide based on the best info you have at the time. Consider all of the pros/cons and then listen to your gut.
Personally, I think I would find it difficult to return to the right seat for 20 years after flying left seat on the Airbus at a very stable airline. I am a long way from that decision myself. Good luck!
