Hi, I wonder the same thing.. I've never heard of the term no poaching agreement, only that it's the rule for QR crew..
What about Ex-Etihad crew who wants to join Emirates ? Can they join EK within a year or no ? I would really appriciate an answer on this ... I'm myself is ex-etihad and within 6 months of quitting Ey, I got to Final interview with Emirates but wasn't offered the job. Does this agreement have something to do with it you think?
