Not sure how the practical application of this idea would work? The senior group gets summer vacations and the first green slips. For the ER that may not matter. For the rest of the fleets the senior guys get their GS and then WS over vacation, getting double pay for time flown in both cases before the junior guys who can't hold summer vacation even get a GS. I'm not a fan of buying or in any way losing vacation value.
I see were you are going though. We need to hold the line with ALPA. The survey is great for participation but lacks in its ability to allow pilots to input their direction. We will have to do it the old fashion way, fill up email and voicemail boxes.
