About setting up departure wave...

Going into long haul with no short haul is usually very ill advised. Looking at ANC wiki there are no trans pacific passenger flights so that suggests direct demand is close to zero, hence why your looking at connections. So your thinking similar to LAX-ANC-NRT. Issue is your going to be competing with everyone going LAX-NRT plus those offering connections already.

Everyone has their own preferences, my model is I would say it is not enough...
