In this paper, we present an approach for transferring delay away from the terminal to the en route phase of flight. We propose a multi-objective integer programming model designed to assign delays to flights well in advance of the terminal. The IP model weights an objective of fuel savings and throughput to assign controlled times of arrival to flights 500 nmi from the airport. A series of trade studies is performed to evaluate our concept. First, the model is tuned by developing a Pareto Frontier to identify weight factors on our objective function. We demonstrate that the model can effectively transfer delay en route. This transfer holds up even with relatively moderate carrier compliance. We go on to demonstrate that this delay transfer yields significant fuel savings benefits on a per flight basis.
