A systems analysis is conducted to show the potential of intermediate stop operations in terms of fuel efficiency increase and cost effectiveness. With existing and redesigned aircraft the fuel-saving potential is in the order of 7 to 15.5%, respectively. A global analysis of all Airbus A330 and Boeing 777 flights served in 2007 is performed, defining fuel-optimum intermediate airports wherever possible. An A330-200 type of aircraft with a design range reduced to 3000 n miles would yield highest global fuel benefits of 10.4% considering both intermediate stop operations flights and flights served in conventional ways. With today’s fleet, only few, very long routes could be served in a more fuel-efficient way than in standard operations. An airport load analysis shows that the top ten selected airports for intermediate stops would serve 30–44% of all flights for the fleets under consideration. These airports would experience additional traffic of roughly 130 flights per day. It is further shown that a cost-benefit analysis is necessary to reveal the true economic benefit of this concept for an airline, going beyond plain fuel cost to a trade-off between opposing cost elements, revenues, maintenance, and utilization.
