loads on first rotations are nothing to go by,as a lot of pax will be press and travel trade. to judge how a route is doing you want 2 months or more to get a true reading. its not bums on seats you want to worry about its yeild. you will never know yeildas airlines dont release that.first flight i would think cabin crew, press and travel trade so yeild would be just about zero,unless they had a subsidy.
