  author={Mark Hansen and Tasos Nikoleris and David Lovell and Amedeo Odoni},
The potential benefit from introducing trajectory based operations into the NAS is estimated in this paper. Delay predictions of a stochastic and a deterministic queuing model, which represent high and low levels of trajectory uncertainty, are compared. It is found that delay savings are on the order of 35% in the average case, Delay predictions from the various models are found to be strongly collinear over a wide range of congestion levels.
