Just look up ‘quid pro quo’. This is a good example. One if my friends best described it as ‘dis for dat’.
Approximately 110 GGN and 278 SKV pilots were added to the Jazz list on a DOH basis. In most cases, that has allowed them to maintain their former status (with some speed bumps for the former GGN pilots). Of these 388 pilots, 50% or more will likely leave for AC once mainline hiring resumes.
In exchange, the Express flying was repatriated to one operator - Jazz - and the work belongs to just one pilot bargaining unit (Jazz ALPA). Effectively a return to late 2009 with the effective transfer of the 15 former mainline E175 airframes to Jazz plus 10 more E175 airframes from SKV.
So, once the dust settles, probably 100-140 pilots will remain at Jazz long term with the 25+ airframes. For some, a reasonable outcome. However, that may not line up with the perspective of any Jazz pilot that lost seniority position to pilots added from GGN and SKV.
