I think the differences in the current fleet are missing. 10% at Delta gets you a FO block line flying a widebody out of NY and high reserve, maybe a block line out of ATL, as well as LA and I think CVG on this latest bid. Going from 767ER line holder to reserve A320 is concessionary for the Delta pilot.
I like the "Fair Plan" from the other site, did you see that? Opportunity for everyone when they choose.
