Herein lies the problem with the PBS discussion at SWA. Your statement is mostly emotion driven with little or no facts to support it. Your statement regarding the CFOs position may be correct, but maybe not. Saying that management will never do something without the conversation taking place is simply irresponsible. Perhaps thta would have happened elswhere/everywhere, but not here. If we had typical airline management, 200-300 of us would be on the street right now.
SWAPA has let emotion drive the conversation rather than fact and used this issue to easily stand up to/against a management desire. I don't think that PBS would achieve the cost benefit management desired with current vacation rules. I do not know the relationship between month-to-month overlap and vacation overlap potential. If SWAPA could get that vacation week to pay in the range of 35-40 trips, I think that we are in the range of a win-win. Problem is, no one even tried.
Our current vacation rules were developed when we had a 3-5 cent per ASM cost adantage over our competittion. That advantage is history and so is the growth that we enjoyed with that advantage. PBS may enable us to gain some of that efficiency or simply hold our own against competitors that are using it.
