Dead Airline’s Emails Just Became a $10 Million AI Prize

Spirit Airlines shut down in May, its second Chapter 11 bankruptcy in two years, leaving behind planes, airport slots and a loyalty program to be sold off piece by piece.

Google wanted none of that. Instead, it paid $10 million at auction for something airlines rarely think of as a sellable asset at all: the internal digital record of how Spirit actually operated, including roughly 100 million employee emails, 500 million Microsoft Teams messages, more than 17 million OneDrive files, more than 20 million SharePoint items and 516 code repositories holding about 30 million lines of custom software, according to an Aug. 14 notice filed in the U.S. Bankruptcy Court for the Southern District of New York. The package also includes more than 175,000 employee records dating back to 1986, along with data on aircraft operations, revenue management and productivity.

Google started the bidding at $5 million and doubled it to win, beating a $7.5 million offer from Mercor, an AI hiring and training-data company that has been named backup buyer if Google’s purchase falls through, according to the same court filing. Bankruptcy Judge Sean Lane is scheduled to review the sale at a hearing on Wednesday (Aug. 19). Google confirmed the purchase, telling Axios it “acquired part of an enterprise dataset from Spirit Airlines, which can be helpful in improving our products and AI models.”

The sale explicitly excludes Spirit’s 97.5 million passenger profiles, roughly 52.4 million loyalty program records and 740,000 co-branded cardholders, according to Skift. A third party will remove personally identifiable information before Google receives the data, using deidentification standards set under the California Consumer Privacy Act, with Google covering the cost of that process and agreeing not to attempt to re-identify anyone in the sanitized material.

A Company’s Internal Records Just Became a Priced, Contested Asset

What makes the Spirit sale notable is not the dollar figure but the category of thing being sold. Corporate email archives, internal chat logs, IT tickets and legacy software code have historically had almost no resale value once a company failed. They were considered a liability to store and dispose of, not an asset a buyer would compete for. The fact that Google and Mercor bid against each other for exactly this kind of material at all is itself new. Artificial intelligence companies call this category proprietary or “real-world” data: records of how an actual business ran day to day, not just the public content available on the open internet.

That shift reflects a specific limitation AI developers are running into. Large language models have already been trained on most of the easily accessible public internet. Continuing to improve their ability to handle complex, realistic business tasks depends on data that captures how organizations actually communicate, troubleshoot problems and make decisions internally, something a public website or a scraped forum post cannot show. Spirit’s operational archive, built up over decades of running an actual airline, contains exactly that kind of texture: real emails between real employees solving real scheduling conflicts and maintenance issues, at a scale and level of authenticity that is difficult to manufacture synthetically.

Bankruptcy Estates Just Found a New Asset to Sell

If Spirit’s sale closes, it establishes a rough price benchmark other bankruptcy trustees and creditors’ committees are likely to notice. Companies liquidating in bankruptcy typically auction off physical assets, real estate, equipment, patents and customer lists because those categories have well-understood resale markets. A company’s internal operational archive, absent an AI buyer specifically interested in it, would typically be treated as a compliance and storage cost to be minimized, not a revenue source.

Spirit’s case suggests that calculation may be changing for any company with a substantial digital paper trail and a genuine operational history, not just failed airlines. Judge Lane’s ruling Wednesday will determine whether that pricing precedent actually takes hold.
