If the aircraft's engine thrust is reduced, by reducing the power the engines generate, less fuel will be burned. This said, over the course of a journey, there will be an optimum altitude and speed for an aircraft to fly at in order to burn the least fuel. This calculation will be the result of a number of things, including how heavy the aircraft is, and how the surrounding whether will affect it.
