We don't know how the membership voted other than that 68% who bothered to vote voted yes and 38% voted no. Was it the senior guys who passed the LOA?? Maybe, but even if the top 25% of the crew force voted yes, the bottom 25% could have negated thier vote with a no. I think if the junior pilots were less apathetic than the crew force in general , the results would have gone the other way. Make a case otherwise, that's my opinion.
