Bulman said such contracts were a threat to the airline's confidential financial information and operational data, as Google may use it for its own future and potentially rival services in the retail space.
At the same conference last year however, Bulman did call for the airline industry to work together on the development of open source apps to serve the whole industry.
In response to Bulman's concerns about wider data sharing at this year's conference, IATA's Popovich said, "The customer would obviously have to give permission."
Another delegate said, "Both courts and government have made judgements on data sharing and what you can do with personal data, but those judgements are often different depending on which country you are in."
