The Spirit Airlines data sale, explained
Spirit Airlines, which stopped flying in May 2026, put its internal records up for sale in bankruptcy: about 100M emails, 500M Teams messages and employee records going back to 1986. Google won the August auction at $10.0M, and micro1 later offered $12.5M. Unions objected and lawmakers raised concerns. The court has not ruled; the hearing is set for 6 November.1,2,3,4,5,6
What is for sale
Not planes, not routes. Spirit is selling a copy of its own internal records. The court filings count about 100M emails across 80,000 accounts, 500M Microsoft Teams items, about 38M OneDrive and SharePoint files, and 175,658 employee records dating from August 1986.2
Passenger records are not part of Google's bid, and a consumer privacy ombudsman, an independent official who looks after people's personal data in a bankruptcy sale, was appointed. Later, Google agreed to drop more datasets, including booking, refund, timecard and WiFi records, with the price unchanged at $10.0M.7,8,9
What happened, step by step
This all runs inside Spirit's Chapter 11 bankruptcy case in New York, filed in August 2025. A bankruptcy sale needs the judge's approval before it can close.10,11
- 2 May 2026: Spirit stops flying.1
- 17 July 2026: a consumer privacy ombudsman, Lucy L. Thomson, is appointed.8
- 14 August 2026: a two-and-a-half-hour online auction. Google opens at $5.0M and wins at $10.0M. Mercor becomes the backup bidder at $7.5M.3
- Mid-August to early September: unions, a software vendor and pilots file objections.5
- 3 September 2026: micro1 files a late $12.5M cash offer, $2.5M above Google's winning bid.4
- 5 October 2026: the ombudsman recommends approving the sale to Google, with an outside firm certifying the cleaning before every transfer.12
- 6 November 2026: the sale hearing, after several delays. Nothing is approved until then.6
Why people objected
The staff who wrote those messages never expected them to train AI. The flight attendants' union asked to exclude their information. Pilots warned that the risk of being identified could put people off confidential safety reporting across the airline industry.5,13
A software vendor, Springshot, said its contract gives it ownership of the data its service generated. And 121 lawmakers, led by Senator Elizabeth Warren and Representative Steven Horsford, wrote to Spirit's and Google's chief executives.14,15
Cleaning became the deciding issue. A filing after the auction said de-identification and privacy "may be outcome-determinative", meaning they could decide who wins. Mercor offered more money if it could do the cleaning itself, and micro1's offer also proposed cleaning in-house, with an independent reviewer checking a 1% sample.16,17,18
Pros and cons
Pros
Cons
What it means for a business like yours
You are not an airline, but the same questions will come up in a much smaller deal. Who owns each record, including data your software vendors hold? Who cleans it, and who checks the cleaning? How will your staff react? Spirit had to answer all three in public.14,12,19
It also shows that the price is not the only thing buyers compete on. At Spirit, cleaning and privacy terms mattered enough to decide the winner. In your deal, asking how the data will be cleaned is not fussy. It is the main event.16
Should your business get in now?
Businesses are already licensing their records: micro1 has committed $1B over 12 months to buying company data, and at least 18 firms started advertising for it between September and mid-October 2026.20,21 Our view, not a promise: the money will not be around forever, because prices tend to come down as more businesses sell.20,22 Take the quiz to see which firms fit your business.
