18 March 2015, c. Leeham Co: In Part 1 of of this series we investigated the market sector 225/5000, which is our name for the market segment beyond the capacity of single aisles A320 and 737 aircraft. Boeing calls this Middle Of the Market, MOM, and is studying which aircraft type would best cover this segment.
In Part 5 of the series we concluded that beyond 220 seats a dual aisle aircraft can be competitive as it can increase utilization due to shorter ground turn-around time. We now conclude the investigation by looking at what Airbus response can be based on a further developed A320 and how it would stack up against optimized seven abreast dual aisle alternatives from Boeing's MOM study, one of these using Boeing's patented elliptical fuselage, Figure 1.
