Also being overlooked is the notion that the airlines are largely going to smaller planes as a result of industry dynamics and the rising cost of fuel. They simply can't afford to run half-empty planes across the country. So Airbus apparently is fighting an economic battle indirectly as well. Perhaps the overseas markets are different such that greater sized aircraft are practical, don't know.
That is just what I was talking about.
My 26 y.o. son is a captain for a regional airline flying 50 passenger RJs. Says they are inexpensive to buy, and cheap to fly. Needs just a captain, first officer and one flight attendant. They are very profitable.
