I think it is a great move by the UAL MEC. Each pilot group has to take the information they have in-front of them and make decisions that will set a course for success. In this case United management continues to take advantage of a concessionary contract. The UAL pilots have had enough... How much longer should they have to wait it has been 10 yrs!
If the UAL ALPA pilots are successful this will set a mark in the industry that shopping for profits from pilots W2 is not acceptable. The message will be sent industry wide that the concessions are old news and we aren't going to take it.
I will gladly join the UAL pilots at my nearby airport and walk the line.
