Google LLC won a bankruptcy auction last week to acquire an enormous archive of internal business records from the defunct ultra-low-cost carrier Spirit Aviation Holdings, agreeing to pay $10 million for what court filings describe as one of the most detailed corporate datasets ever sold to an AI developer. The bid covers 100 million emails, 500 million Microsoft Teams chats and collaboration records, and information related to revenue, aircraft operations, employee productivity, and audits and fraud, according to an Aug. 14 notice in the U.S. Bankruptcy Court for the Southern District of New York. The purchase also includes more than 175,000 employee records dating back to 1986. Google beat out a $7.5 million offer from AI talent recruiting company Mercor.io Corp., which was named the backup buyer if the Google sale falls through.
The sale is the direct product of Spirit's singular collapse. The transaction is unusual even if airline bankruptcies are not: most bankrupt airlines are purchased whole, including their data, by another carrier, but Spirit was the first significant U.S. airline in 25 years forced to halt operations entirely rather than be sold to another airline. Spirit filed for bankruptcy a second time in August 2025 following losses of nearly $257 million after emerging from its first bankruptcy in March of that year, with a spike in jet fuel prices tied to the U.S.-Israel-Iran conflict pushing its projected 2026 operating margin toward negative 20 percent. The purchase explicitly excludes customer data on Spirit's 97.5 million passengers, its 52.4 million loyalty members, and 740,000 co-branded cardholders. According to a court filing by PJT Partners vice president Dylan Friesner, an investment banker for Spirit, the data does not contain any personally identifiable information and will be deidentified, meaning it will not be associated with individual people, with the buyer agreeing not to attempt to re-identify the users.
The deal's clearest legal obstacle arrived Tuesday when the Association of Flight Attendants-CWA, AFL-CIO, representing roughly 5,500 former Spirit cabin crew members, filed a formal objection in the Southern District of New York. The AFA argued that the deal's privacy provisions are designed to protect consumers, specifically passengers, but not employee data, raising concerns about the underlying confidentiality of disciplinary records, payroll history, and internal communications. "With a group the size of the Spirit Flight Attendant population, our union has significant concerns that it may be possible that information about identifiable individuals or small identifiable groups can still be reconstructed and determined," the AFA stated. The union's court filing articulated a concrete re-identification risk: a pseudonymized dataset can still disclose which crew bases generated grievances, how a small subset of flight attendants performed on recurrent training, which employees were subject to investigation, and what employees said to one another about management, staffing, or their union. The AFA asked the court to reject the sale unless changes are made to exclude all flight attendant information, including training records, time cards, and payroll, as well as any Microsoft 365 content containing flight attendant data.
A U.S. bankruptcy court on Tuesday delayed to September 9 a hearing to approve the sale, with the adjournment coming directly after the AFA filed its objection. The U.S. Trustee, a Justice Department bankruptcy system watchdog, has appointed an independent consumer privacy ombudsman in connection with Spirit's sale of assets. The ombudsman's mandate, however, focuses on consumer records, not labor ones, a gap the AFA's filing makes explicit. The union has also requested a condition barring Google from using the data to profile any identifiable group of flight attendants, along with clearer rules on whether the material could later be passed to other third parties. Google, for its part, has maintained that it will not receive any personal information from the dataset and that any data it receives will be rigorously scrubbed of any personally identifiable information by a third party before receipt.
If Judge Sean Lane signs off on September 9, the bankruptcy court will have effectively ruled that a defunct company's internal communications are a freely transferable commodity, a precedent every AI lab and every labor union will be citing for years.
