Judging from the airline names, I would guess most of you are European. I left for the US almost 2 decades ago (family reasons). All carriers here are seniority based with union. There is not a change that will change. Also T&C's here at all the LCCs (at this moment) vastly better than at all LCCs in the EU. Because we can only do our job just as good as the next guy (SOP) seniority makes sense, having a union prevents other pilots from undercutting pay. The results speak for themselves.
