Twin Aisle Aircraft for Short Range Operations - An Economically Attractive Alternative?

Short range air tra�c is dominated by single aisle aircraft. The average seat count of delivered single aisles has grown considerably. Single aisles are handicapped by lengthy boarding and deboarding times. Aircraft with twin aisle cabin layout may alleviate the boarding problem. But those aircraft may su�er from increased cost of operation. This paper studies how much better twin aisles fare in turnaround operations and how much more they cost to operate. These �gures are analyzed for a selection of capacities and mission ranges in order to analyze where twin aisles o�er bene�ts. The general �nding is that twin aisles are more suitable above 240 seats capacity, but may o�er superior economics even for lower capacities at short distances.
