Since the AIP bullet points came out, the biggest issues I heard pilots complain about were the weak COLA increases, no 321 payscale/override and profit sharing. I think if they would have gotten more gains in those 3 areas, this TA would be an easier pass.
Reading the TA Highlights, the scheduling and pairing construction section are pretty good and that's where they got the most gains, but then again, a lot of that stuff is industry standard that other airlines already had in place, we are just so beaten down working under the crap FSM/PEA for so many years that those sections sound amazing now.
The biggest issue for me is the Implementation timeline! There are some absolutely ridiculous timelines. Why does it take until 1/2019 to give the reserves that extra day off? We all know the company is going to take their sweet time to implement that stuff as close as possible to December 2019! That is over a year away!
