This is actually a very average result considering the strength of the market and huge profits at other airlines. The effective losses on the Saab fleet totally highlight that this is unsustainable - meaning that there is just no profits to pay for new replacement fleet. Too many of the Saabs are flying half empty and subsidised by the tax payer. Some of the routes are probably better off with Cessna Caravans
To be honest, the 737 fleet should make more than this to be long-lived. What happens when the Saabs are 40 years old?
