I'm at a WO but I'm treating it as the flow doesn't exist. The bonus and the upgrade times got me to come over.
HOWEVER, with the increasing lack of applicants, it's becoming more and more likely the big 3 will do gentlemen's agreements. As in they won't poach each others WO pilots. So it could be quite possible for me to never see United or Delta. But until it happens it's all rumor.
