That would depend on the intent of the scope section. As you've outlined, the goal is a mutually beneficial code share.

Scope failures are more directly related to alter ego replacement of our airline's pilots:

• Does the action increase or decrease the number of pilots employed (and represented) at Delta Air Lines?
• Does the action increase of decrease the representational power of the Delta Master Executive Council?
• Does the action protect the seniority & longevity of Delta pilots?

Based on objective criteria, the Alaska codeshare is controversial, but not clearly a "scope fail" in the same way the Compass divestiture was.
