They are not losing Delta. DPA has been around for a year now. They are not even close to getting the cards they need for a election and the cards they have on file are starting to expire. It will never even come to a vote. There have been past efforts at DAL after a merger and pilots who don't like the seniority list result try to change unions. I believe after a year of trying they have only about 2500 cards and they need 6000 to even call for a election.
