WASHINGTON, July 22 (Reuters) - Three Democratic

senators pressed Delta Air Lines ( DAL ) CEO Ed Bastian to

answer questions about the airline's planned use of artificial

intelligence to set ticket prices, raising concerns about the

impact on travelers.

"Delta's current and planned individualized pricing

practices not only present data privacy concerns, but will also

likely mean fare price increases up to each individual

consumer's personal 'pain point' at a time when American

families are already struggling with rising costs," Senators

Ruben Gallego, Mark Warner and Richard Blumenthal wrote in a

letter dated Monday and made public on Tuesday.

The airline said in a statement, "There is no fare product

Delta has ever used, is testing or plans to use that targets

customers with individualized offers based on personal

information or otherwise."
