Wow, who knew that LM was running Delta airlines! I missed that part. Management decides on who they merge with not ALPA or any other union. Management also controls the seniority list and decides who goes on that list unless you have a specific contractual item. That point is forgotten over and over again or never really understood. Some pilots actually think their union or another union could simply decide to integrate another airline into their list. It simply does not work that way.
