I think you are thinking bases? MSP, ORD, DTW are bases. Everything starts and ends there on most trips. If you get a MSN overnight, it's just that, an over night. I know we do MSN stand ups, but those are basically quick overnights. Those are pretty mixed in seniority. We also do turns, which are just like they sound. People get off, people get on. I don't believe that any airline has MSN with long stays. Like you said it's just a spoke, and typically it's just a short one
