EVERY pilot on the APL, ALL 1700, were offered a MDA position, with maybe the exception of those wanting to go but were held at a J4J carrier. When the first class of CEL pilots went to MDA, they knew they were going to be on the AAA seniority list as an AAA pilot. Period. In order for the first CEL pilots to bid over, that meant EVERY APL pilot was offered a position and accepted or passed (again with maybe the exception of those held at a J4J carrier).
As far as adjusted LOS, if someone junior to you was given LOS credit for MDA, and you did not go, you were brought up to there LOS to preserve relative position on the seniority list.
When the pilots on the APL were offered a position at MDA it was stated that MDA would operate on its 'own certificate' (originally planned as the old Potomac certif.) and would operate separate from US Air mainline. That is how it was 'sold' to the APL pilots; turned out they could not use the old Potomac certificate, and the decision was made to put the E-170s on the US Air certificate. Had the APL pilots been told, right from the start that it was actually a 'recall to mainline' and they would accure mainline longevity, I believe many would have decided differently. You think???
How many APL pilots out there were told that if they went to MDA that they would be operating on US Airways 'mainline.' Let hear it??
Plain and simple, the company and ALPA screwed that up royally!!!
