This document discusses how airport and airline technology managers can collaborate to improve the customer experience and efficiency of the passenger journey. It argues that by sharing and fusing data between airports and airlines, using technologies like passenger tracking, they can gain benefits greater than if working independently. Specifically, accurate data exchange about passengers, flights, and operations across touchpoints can help predict delays, optimize processes like border control and baggage, and personalize assistance. Formal relationship management structures and forums are needed to promote collaboration, build trust through joint problem solving and trials of emerging solutions.
