To my mind it's pretty clear. If you absolutely want long haul, join BA (or Virgin). If you can cope without it, join EZY. I've worked at both companies and was considerably happier at the latter, and was treated considerably better.
BA will continue to push around and abuse its crew until recruitment becomes impossible - it's clear that's just how WW and AC have decided to operate. Until then, why make things better? These people have no conception of what working in the toxic company they've created is like. You can almost picture them at an expensive restaurant somewhere discussing the next barrage of cuts, productivity hikes, or strategies to break our resolve - just as their bottle of desert wine and 4 figure bill arrives. Meanwhile people line up to join BA on nothing but the industry rumour that it's still the best place to be. I fell for it too.
I was unlucky, I joined BA before I had a chance to move seats at EZY. I will however wait it out and move back as soon as I can.
