I spoke directly with a lawyer at the ALPA MEC office for Eagle. I was told that if I were seat locked that my 3P would be ignored. I had no ability to preference bid anything in the displacement except for the equipment I already fly. Only my 3D was necessary to fill out if I did not want to proffer to displace to DFW on the ATR. It was explained to me that 3P would go towards vacancies that I wasn't seat locked out of (ie the aforementioned DFW ATR) and 3D would be valid if I were displaced.
My feeling is this whole thing is absolutely screwed up and should probably be voided and rebid. There are too many errors in it -- and it was not explained in any way, shape or form that could be considered adequate for something with so great importance. I'm not even sure those examples were in English. I'm not a lawyer, don't pretend to be, don't play one on TV -- what chance did any of us have understanding 1/2 the crap the company put out? I don't understand legalese.
