IATA has found in a new survey that the majority of passengers (65%) are willing to share personal data for expedited security and 45% are willing to replace their passports with biometric identification.IATA's One ID project aims to move passengers from curb to gate using a single biometric travel token (fingerprint, face or iris). But concerns over data protection must be addressed.”As we move more and more towards digital processes, passengers need to be confident that their personal data is safe. IATA is working to establish a trust framework that ensures secure data sharing, legal compliance and privacy,” said Nick Careen, IATA's Senior Vice President for Airport, Passenger, Cargo and Security.Passengers want more self-service options. Automated check-in was preferred by 84% of passengers. Most (47%) prefer to check in online using a smartphone. Only 16% preferred traditional check-in.Some 70% of passengers want self-service baggage check-in. Only one in three travelers prefers an agent to tag their bag. The electronic bag tag is growing in popularity – favored by 39% of passengers (up 8 percentage points from 2017).
