I don't know who is leaking what, but I do think it is fairly obvious what is going on...
It is widely accepted/believed among the DAL folks that DALPA's opening offer was DOH if the company would buy out the top 2000 or so NWA guys and send them into retirement paradise. This would put the two groups on fairly equal footing as far as average time on property goes. This did not fly because DAL would not fund it. Now you have an impasse...Hmmmmm? To say the managers want this merger is a huge under statement. The longer it takes, the more nervous they will get...and the more willing they become to pony up the funds to make it happen. I think ALPA finally has a strong hand and they are playing it well!
The beauty is neither pilot group needs this merger, but the CEO's do! So let's not argue over which pilot group has to give up what, but focus on what the companies need to fork over to make a merger beneficial for all pilots. Maybe I am an optimist, but I think that is exactly what the two negotiating teams are doing.
