Unfortunately plas teek not all airlines around the world run on a handout charity basket case basis like Air NZ. They actually have to make money which is why only half the world is flying Boeing any more.
If you're in the airline business and required to turn a profit then you need to operate both types or you end up paying too much. Ask anyone in engineering about 777 parts prices. If you're in the flying game for fun then you can pay Boeing whatever they ask, everything they say you will believe. Are you going to tell me the 'bus stall protection is a bad thing too?
If your engineer is having troule turning the aircraft around maybe you should change engineers, plenty of other 'bus operators don't have the same problem.
