Understood, althouth I think you and 700 are arguing semantics and it depends how you define "merge." The point is those routes, employees, equipment, etc. were "merged" into the UA system, and there were stockholder, regulatory and union issues to overcome to accomplish that.Bear,
UA never actually "merged" with PA. They purchased its London authority and its Pacific system, in effect helping break it up. The balance went to Delta.
And, perhaps UA will collapse and LCC will purchase portions of its system, effectively helping break it up, or maybe vice versa. Either way there will be regulatory, stockholder, labor, etc. issues as well.
