The company staffs for summer flying, next year. It is a dance with more than one step.

Network planning puts the music on. Crew Resources builds a model to cover whatever network plays. Then they have to staff up First Officers to cover mid seniority pilots who will bid up from the right seat. Then they have the "big bid" with the majority of Captain's slots. Then fill the holes.

Network planning's music selection works little better than my two daughters fighting with Amazon's Echo between the soundtrack for Hamilton or Frozen. As soon as "I'm not giving up my SHOT SHOT" comes on Alexa is ... "let it go, let it go"
