> I would suggest the next step from the B737-900 would be the Airbus A321. > According to the Airbus web site that holds up to 220 pax. 220 pax on a A321 seems like cruel and unusual punishment. Airbus is really reaching on that one. The smaller version of the 7E7 (approx. 200 pax) will probably fill this end of the BA line. I know the 7E7 is still basically just vaporware, but has anybody seen the projected fuel burn per hour for the base version? > I can't see Boeing producing another B737 model. Like the 757, the venerable 737 has probably been strectched and modernized to its limits.
