Bonza is adjusting capacity to demand, they have axed a whole pile of routes, they don’t appear to be flying around empty as such.
The issue for Rex, is they have placed all eggs in one basket, that’s capital city runs. I don’t know who the Rex corporate traveller is, I assume SME. However the Rex passenger appears to be Leisure VFR and very very small SME. That makes sense, as Rex is pretty full from Friday to Monday, as alluded to above, no denying that. But, they have issues during the week. They are playing middle of the market carrier with no loyalty program, that will leave you exposed mid week.
But to be flying 40/50 people around on a dozen flights mid week indicates some strategy problems at hand. Rex will need some fresh eyes to take it any further, they are most certainly stuck in 1981.
