Maybe because the posts in answer to the "improve reserve crowd" invariably gets the cursory, "Yea, it's bad but there are other things more important" The fixes to reserve you mentioned are now Delta standard. Many act like that will use too much negotiating capital to get your aforementioned industry standard improvements and is too big of a hill to climb because it may come at "their expense". That leads them to continue to push "fix reserve", in an attempt to get buy in from the more senior guys. They want a unified front on "Fix reserve now dammit" before they can move on to your other bigger items.

Other than pay, which will be industry leading (even mgt knows that), what "other bigger items" are of concern to you? Believe me, you will get buy-in from the "fix reserve crowd". But, it won't be, "Do your stuff and then if any "negotiating pie" is left over sweep the crumbs towards fixing reserve" which the senior guys appear to tout..
