Delta Air Lines has publicly stated that it is not using artificial intelligence (AI) to set personalized ticket prices based on individual customer data, responding to criticism from U.S. lawmakers and public concerns. The airline emphasized in letters to Congress and public statements that no fare product currently in use or planned involves individualized pricing driven by personal data. Despite this, Delta has acknowledged employing AI through a software partner, Fetcherr, which provides a "super analyst" capable of processing large volumes of aggregated data to assist analysts in revenue management. This AI-driven dynamic pricing system is expected to be applied to about 20% of domestic routes by the end of the year. The program is designed to optimize revenue by analyzing broad data patterns rather than targeting individual customers. However, the complexity and rapid fluctuations of AI-influenced pricing have raised regulatory and consumer concerns about fairness and transparency. The U.S. Department of Transportation, led by Secretary Pete Buttigieg, has indicated it will investigate any airline using AI to personalize ticket prices. Industry observers note that airlines, including Delta, are entering an "exploitation phase" of AI pricing, which could significantly impact the future of travel booking. Delta continues to deny misinformation suggesting it uses customer-specific data for fare setting, while the debate over AI's role in airline pricing and its regulatory oversight remains ongoing.
