Ok so there's one chap saying that Comair have made a loss and one saying they have made a profit. Perhaps the quote of the original poster made allowances for the cost of aquiring the 733s from Qantas.
I seem to recall SAA claiming to have made a profit a few years ago when all they did were sell off a few aircraft. I guess what would be revealing is to see what operating profit they made and a break down for Kalula would be nice to see.
Are the drivers of the 732s able to fly the 733s and 734s given the performance differences and EFIS etc?
