I think integrating Compass could be a good thing if it is paired with change in the scope language. All future 51+ seat (or 71+ if you'd prefer) flying is flown by Delta pilots on the Delta seniority list. As contracts expire they are flown by Delta pilots.

Delta already has 153 DC-9-10 equivalent "RJ"s flying for them. That could mean an eventual 1500 more Delta pilots.
