Two Things.
1) endeavor and delta are both part of the same company, OO and United are two completely different companies, same with WN and FDX. Endeavor is part of the same company we are, we are just different subsidiaries.
2) the reason they changed it was because retirees were bumping active employees trying to get to work and delta was spending $$$ to buy active employees a seat so retirees could travel. (like it or not from delta’s perspective endeavor are active employees as they are employed by Delta inc to fly planes for delta) They will not go back to that. Just from a business sense it makes mores sense to have 9E above DL retirees, and I doubt we will be willing to give up any negotiating capital to change that. If you still work here and want it fixed, focus on section 1 of our PWA
