Delta Air Lines is using AI technology to determine a small percentage of ticket prices. Find out what this means for consumers.

Fetcherr is one of the prominent suppliers of AI-powered dynamic pricing, and it already works with several airlines, including Delta, Azul, Virgin Atlantic, WestJet, and Royal Air Maroc, according to Aviation Week. Delta has said it doesn't share personal customer data with Fetcherr.

U.S. Transportation Secretary Sean Duffy said Tuesday the department has concerns about the use of AI to set personalized airline ticket prices and will investigate if anyone does so. Last week, Delta Air Lines told lawmakers it will not use AI to set prices for individual consumers.
