The IRS accessed a database of hundreds of millions of travel records, including flight times, locations, and credit card information, without a warrant, according to a bipartisan letter to airlines. The letter, shared with 304 Media, reveals that major airlines such as Delta, United, American, and Southwest funnel customer records to the Airlines Reporting Corporation (ARC), which sells access to government agencies. The IRS case is the clearest example of how agencies are retrieving massive amounts of travel data without proper legal procedures. Lawmakers urge airlines to shut down the data selling program, which allows agencies to buy access without warrants, court orders, or similar legal mechanisms. An update states that ARC said it already planned to halt the program following the report. The IRS confirmed in the letter that it did not follow federal law or its own policies when purchasing airline data from ARC. The letter emphasizes that the IRS did not conduct a legal review to determine if the purchase required a warrant. This revelation has prompted calls for stricter oversight of government data access and transparency in information sharing between private entities and agencies.
