I assume that the system can handle the same if not more JFO upgrades than initial FO training. If they start taking DEFO's when some guys have been waiting well over 4 years for a JFO course then it is outrageous. Why should we suffer due to the companies short sighted training, why were they not getting ahead of the game when times were slow. I remember reading not that long ago that the plan was to have SOs doing no more than 3 years before an upgrade.
