High-tech investments and automation can improve the airport experience but they aren’t a cure-all, according to a survey of 2,000 travelers by OAG, the airline data company. Among the findings: Nearly 60 percent of travelers would let airports track their location through a mobile or wearable device to allow redeployment of staff to cut down on wait times; only 19 percent said they see value in interactive robots that provide information and concierge services; 40 percent want more baggage loading zones to expedite security lines; 54 percent would value in-airport, turn-by-turn directions for navigating terminals and gates; and 74 percent want real-time updates on expected boarding times. Also, 54 percent of millennials, 37 percent of business travelers and 35 percent of all travelers reported interest in self-checkout retail options at the airport.
