Over 100 U.S. lawmakers have expressed serious concerns about a proposed agreement between Google and Spirit Airlines, which involves the transfer of internal Spirit data to the tech giant for artificial intelligence training, in exchange for $10 million. The data set in question includes a vast array of sensitive information: 100 million emails, 500 million Microsoft Teams messages, employee contracts, timecard records, and payroll details. Although Google has assured that all data will be deidentified by a third party, Representative Steven Horsford and 113 other federal lawmakers worry that these measures may not suffice to protect privacy in the era of sophisticated AI technologies. The lawmakers' letter, led by Horsford and Senator Elizabeth Warren, emphasizes that removing direct identifiers like names and email addresses does not guarantee anonymity. The concerns are particularly poignant in Nevada, where nearly 1,000 Spirit employees lost their jobs after the airline's closure announcement in May. Lawmakers have urged both companies to implement a more robust deidentification process, consider feedback from former employees, minimize the amount of employee information shared, and establish clear boundaries for data usage. They also recommend an independent employee confidentiality review. Google has reiterated that it does not seek to acquire personal information and intends to handle the data responsibly. With Spirit Airlines no longer operational, they have not issued a statement.
