Good point, but the only consideration in getting multiple WS (in seniority order) is being legal and available. You can't do 2 GS unless everyone that wanted a first, and is legal and available, has had their first.

In addition, using the loophole of the SB/SWF, junior guys have been able to work with their friends to maximize their schedule. You can't ride someone else's seniority for a GS.

Furthermore, SWP is broken, because of SB/SWF, and because we process WS before SWP. A senior guy can't easily improve his schedule without resorting to the gamble of dropping a trip, to WS back his own trip or better. Unless he's unlucky, and people even more senior pick up his rotation AND his target rotation, which they may or may not give to a friend.

In theory, you're absolutely correct about WS being in seniority order, but in reality, the flying that's moving around as a result of the WS process is not necessarily respecting seniority. Let's face it: there are guys getting around seniority by bidding socially with their buddies, and are steering more of the flying their way. Now they want special rewards for it.
