Why are there not more non-stop flights out of Houston?

Andrew: Because unlike other airlines, Southwest Airlines operates on a point-to-point system. This means that we go from one city to another city picking up passengers that all want to go to the same destination. Kind of like a school bus route. Some airlines work on a hub-and-spoke system. This is as it sounds, like a bicycle, where that all flights come to the same airport (hub) and then go to their final destinations (spoke). Southwest has determined that it is more finacially effective to operate on a point-to-point system.

Thanks for the great question.
