The TA'd scope section at AT does raise it to 86 seat jets from 70. A cap of 15 of these new jets, with 5 more allowed under certain (growth) conditions. However those who are justifying that section say that it is because they currently lack comprehensive holding company scope. IOW, the company could do far greater long term damage later with regards to outsourcing within the corporate shell game, so they aren't "selling" up to 20 seats in that seat range but more like agreeing to what can be imposed on them right now anyway in exchange for comprehensive holding company scope. That is how some are explaining it at least. In any case, regardless of AT's impending new floor (assuming it passes ratification), all other majors (except JetBlue) have such scope already at the 70-76 seat limits, and as such will not be in the position to be extorted in the negotiating room over that issue. Any scope give aways from any legacy pilot group will simply be tiny little trinkets that no one appears to be receptive to in the slightest.

This is by no means a "game changer" like you are suggesting it is. I know pilots like to look at trends. That's a wise thing to do. But it doesn't mean every trend continues forever otherwise everytime you apply takeoff power that trend means you're going to be going mach 5 pretty soon, every time you turn you're going to roll and every time you slow down it means you're going to stall. Trends can be reversed. Look for it WRT scope. Some regionals not that long ago at all had 4 engine planes that sat well in excess of the current 70-76 seat limits. That has been sucessfully reversed by, drumroll please, scope...and the wheels were put in motion for that to happen even before the boom/bust contracts of 2000-2001 where scope in volume was sold in good times for a cookie and again in bad times for "bargaining credits" to be applied to cuts.
