We consider design of skyport locations for air taxis accessing airports and adopt a novel use of the classic hub location problem to properly make trade-offs on access distances for travelers to skyports from other zones, which is shown to reduce costs relative to a clustering approach from the literature. Extensive experiments on data from New York City show the method outperforms the benchmark clustering method by more than 7.4% here. Results suggest that six skyports located between Manhattan and Brooklyn can adequately serve the airport access travel needs and are sufficiently stable against travel time or transfer time increases.
