I know there has to be a vacancy. Displacement rights at some airlines include the right to bump a junior pilot in any position when an involuntary displacement occurs, and priority to return to your previous position when a vacancy is posted.
Do the displaced DTW FOs have first priority to return to DTW. (even if someone more senior than them wants the position). For example a SJU captain who wants to go back to DTW vs. a displaced FO who is now in FLL.
I already know that involuntarily displaced pilots have the right to bumb at spirit, but do they have first priority to return to their previous position when a vacancy occurs?
