I think ALPA's main focus has become nothing more than staying in business. There are too many diametrically opposed interests to have a coherent focus that suits ALL members. It seems that doing or saying anything to appease certain member groups is acceptable as long as each group is satisfied enough to not change representation.
This observation admittedly comes from a former member, but I was a dues paying member and volunteer for close to a decade. I have much more faith that my representational needs are being met by an in house union. And, my current collective bargaining group does it for half the price that ALPA is charging most members.
