Why do we need new A/C in the first place? Are the current ones unairworthy? I doubt it. The main reason for new A/C is to please the ever increasing numbers of travelling public. Keep the old birds (we in GA have to) & make the ticket prices reflect the equipment level. I reckon that the travelling public only expect new planes because the hipe is so constant & in yr face. The constant delays of new A/C type show one thing, where simply not ready!
