A software, EasyPOST, is used to show how trajectories for commercial suborbital human spaceflight can be customized to meet the demands of the paying passenger by the manipulation of vehicle performance variables. This software is a powerful tool that provides a large range of potential output variables and allows simple to complex trajectory modeling with built-in atmospheric models and higher-order gravitational parameters where applicable. EasyPOST has the unique ability to analyze case study with low computation time, allowing for a large amount of trajectories to be simulated. A menu of suborbital spaceflights can be weighted to determine the best possible flight for a set of predetermined passenger types. A variety of different profiles can be generated, weighted differently, and selected but it would be better to model many different vehicle profiles to determine which flight profile gives the best ride to a paying customer.
