To airport officials, the taxis are one piece of a larger transportation puzzle to be solved, with the ultimate goal of creating the best experience for travelers. Shuttle buses, limos and other types of shared transportation will also be joining taxis on the lower levels once the curbside changes are fully implemented. The changes will have the most impact at Terminals A, B, C and E, which have a different layout than Terminal D, where the baggage claim, as well as taxis and several other transportation options, are already located on the lower level. “The reality is given the shifts in the marketplace and the consumer dynamics, it’s really creating more congestion on the upper level than what it was designed for,” said Ken Buchanan, DFW’s executive vice president of revenue management and customer experience. “Our goal was to try to balance the upper and lower levels. If we do that, we can create a more safe and more fluid environment.” That balancing act must acknowledge a clear reality, Buchanan said — consumers are choosing ride-hailing vehicles over taxis at an overwhelming rate. Since arriving at DFW Airport in summer 2015, ride-hailing services have seen an eightfold increase in usage through February of this year and now dwarf the number of taxi rides. Taxis, meanwhile, have seen a 42 percent decline, with roughly 1,000 fewer daily rides compared with three years ago.
