I "think" enough mainline pilots have gotten the clue that scope giveaways are a bad deal in the longrun...
Bad for job security for the bottom 20%. Bad for upgrades for the next 30%. Hopefully that's enough folks to carry the day.
The top 10% will give away anything and everything for a $1 raise. Hell, they'd give away all of the narrowbodies in exchange for a starbucks gift card...what do they have to lose?
