Google bought Spirit Airlines emails for AI — senders never consented

Google will pay $10 million for 600 million Spirit Airlines internal messages under a deal that goes before a Southern District of New York bankruptcy court today, August 19. The package includes 100 million emails, 500 million Microsoft Teams chats, 7.5 billion passenger transaction records dating to 2008, 7.2 billion competitor pricing records, and more than 175,000 employee records from 1986 onward. The intended destination is AI model training. Spirit Airlines’ 10,000 former employees were not consulted.

The sale emerged from Spirit’s January 2025 Chapter 7 liquidation. When a US company files for liquidation — as opposed to the reorganization protections of Chapter 11 — its assets, including internal communications systems and the data they contain, become the property of the bankruptcy estate. A trustee is appointed to liquidate those assets for creditors. Internal email archives, Teams channels, and HR databases are assets in the same legal sense as the planes and gate leases. Workers who generated that data have no standing to object to its sale.

Google’s only competition was Mercor.io, an AI-focused recruitment firm that bid $7.5 million. Google outbid Mercor by $2.5 million. The presence of an AI hiring company as the sole competing bidder suggests that bankrupt companies’ internal communications are already a recognized asset class for AI training — and that the Spirit auction will not be the last of its kind.

Google has committed to having a third party ‘rigorously scrub’ all personally identifiable information from the dataset before Google receives it. Customer credit card data and loyalty program profiles are explicitly excluded from the sale. What remains after scrubbing, per Google’s representations to the court, will be anonymized communications and operational records that preserve the structure and vocabulary of corporate language without identifying individual senders. Whether that standard meets any employee’s reasonable expectation of privacy is a question the court is not being asked to answer.

The price tag underscores a mismatch that privacy advocates have flagged since generative AI entered the enterprise data market. A decade of internal communications from a company with more than 10,000 employees — meetings, strategy documents, HR files, contract negotiations — sold for less than the cost of a modest Manhattan office. For the bankruptcy estate, $10 million is money recovered for creditors. For Google, it is a remarkably cheap source of real-world corporate language data that would cost vastly more to generate synthetically.

If the SDNY court approves the sale today, the transfer process begins immediately. Former Spirit workers have no legal mechanism to request deletion of their records from Google’s training pipeline once the sale closes. US bankruptcy law does not grant employees data-subject rights over corporate communications they generated on employer-owned systems. The European General Data Protection Regulation would have complicated this transaction significantly for a European carrier; Spirit’s American jurisdiction made it straightforward.
