I actually called the communications dept in Herndon VA about this. Well actually a year ago before when they announced that 47 crjs were being transferred from one alpa to another alpa. We get weekly email regarding NAI, and other bs. Yet nothing about the aircraft exhange...
The answer they gave me was that each mec had to approve every snippet of news and each mec controlled what the rest read about. So in other words some cowardly PSA mec members decided not to let everyone else know about it. So much for actual news. At this point I realized alpa was worthless.
