Why does Airbus feel that they need to reinvent the wheel with their aircraft designations? As one of their largest North American customers, we would have preferred they stay with convention and refer to the airplanes as such:
A320-10 (A318)
A320-30 (A319)
A320-50 (A320)
A320-80 (A321)
Of course, the early system of A320-100 and A320-200 would have been acceptable also.
- redtail, wrencher and box slammer of A320-151's and occasional driver of short buses.
