I'm amazed anyone is complaining about having RAW buckets that are too large. I assume this is because the complaining is done by pilots so junior they've never seen the old system.
The problem with the RAW system was that it abbrogated seniority, and prevented the flying from being assigned on a seniority basis. It's not just a question of whether one flies, but a question of how flying is distributed among those that have to fly.
The full Low AND High yellow system was so sweet that junior pilots couldn't always get reserve at all. This meant people could slip into lines sooner, and only a small portion of the guys would fly a lot, and those guys would quickly hit the limit, which was good for them (commuters would get done, and go home for the rest of the month), and good for GS opportunities for all.
The bottom line is that arguing for small RAW buckets is arguing for the company's objective, which is to have everyone come up at the same time, so noone benefits. You're saying it's not fair that anyone has a good deal, so we might as well all have... a RAW deal.
Please list me in the camp that says any RAW bucket, no matter how large, is always too small. We don't need no RAW buckets.
