Google's $10 Million Spirit Data Deal Clears Union Privacy Hurdle

Google's $10 million purchase of Spirit Airlines' internal data — including 500 million Microsoft Teams chats and 100 million emails — cleared its biggest remaining privacy hurdle this week. The deal now sits one step from final approval in bankruptcy court.

The Association of Flight Attendants said Tuesday it had reached an agreement with Google, alongside other unions, to protect personal data of former Spirit staff. The union called the agreement "an historic win for worker privacy protections."

Why was the sale stuck in court?

Spirit ceased operations on May 2, 2026, and its assets went to auction. Google won the bid in August, paying $10 million for a trove of internal communications and documents. Google has said the data would help improve its products and AI models.

The sale stalled in bankruptcy court over privacy concerns. The disputed material covered details of both Spirit staff and customers. Last month, 121 members of Congress, led by Sen. Elizabeth Warren, formally raised concerns about the transaction.

A court-appointed privacy ombudsman then recommended approval after personal information on 97 million Spirit customers was excluded from the sale.

What did the unions win?

Aviation unions and public-interest groups withdrew their objections Monday night after striking a deal with Google covering employee data. Under the agreement, Google will not receive:

• Employees' medical and disability history
• Drug or alcohol testing records
• Payroll records, among other categories

The AFA said it also secured a more rigorous de-identification process than originally planned. Google is prohibited from attempting to re-identify the data.

"Worker data privacy in the age of AI has become a whole new worker's rights issue," said Sara Nelson, international president of the AFA-CWA.

"Without our union, there would have been no one to speak for workers in this fire sale of their private information. We fought and we won brand new protections," Nelson added.

She said the union will now push the issue to all of its employers through contractual protections, and will demand federal and state legislation to protect workers everywhere.

What has Google said?

Google did not immediately respond to a request for comment. Last month, the company told Reuters it was "not looking to buy any personal information from Spirit."

"The information will either be completely excluded or will be de-identified by an independent third party before Google receives any data," the company said in a statement.

What does this mean for data practice?

The case sets a template for what happens when a company holding sensitive employee and customer data collapses. Bankruptcy auctions can put that data on the market unless unions, regulators or lawmakers intervene — and here the intervention worked, but only after a court fight, congressional pressure and a privacy ombudsman's review.

The carve-outs were won, not granted. Companies buying distressed data assets should expect unions to demand exclusion of medical, payroll and testing records, plus third-party de-identification and re-identification bans, as the new baseline.

Expect worker data privacy to move from a niche labor issue to a standard negotiation item as AI training corpora become acquisition targets.
