404 Media: “Most people probably have no idea that when you book a flight through major travel websites, a data broker owned by U.S. airlines then sells details about your flight, including your name, credit card used, and where you’re flying to the government. The data broker has compiled billions of ticketing records the government can search without a warrant or court order. The data broker is called the Airlines Reporting Corporation (ARC), and, as 404 Media has shown, it sells flight data to multiple parts of the Department of Homeland Security (DHS) and a host of other government agencies, while contractually demanding those agencies not reveal where the data came from. It turns out, it is possible to opt-out of this data selling, including to government agencies. At least, that’s what I found when I ran through the steps to tell ARC to stop selling my personal data. Here’s how I did that:

1. I emailed [email protected] and, not yet knowing the details of the process, simply said I wish to delete my personal data held by ARC.
2. A few hours later the company replied with some information and what I needed to do. ARC said it needed my full name (including middle name if applicable), the last four digits of the credit card number used to purchase air travel, and my residential address.
3. I provided that information. The following month, ARC said it was unable to delete my data because “we and our service providers require it for legitimate business purposes.” The company did say it would not sell my data to any third parties, though. “However, even though we cannot delete your data, we can confirm that we will not sell your personal data to any third party for any reason, including, but not limited to, for profiling, direct marketing, statistical, scientific, or historical research purposes,” ARC said in an email.
4. I then followed up with ARC to ask specifically whether this included selling my travel data to the government. “Does the not selling of my data include not selling to government agencies as part of ARC’s Travel Intelligence Program or any other forms?” I wrote. The Travel Intelligence Program, or TIP, is the program ARC launched to sell data to the government. ARC updates it every day with the previous day’s ticket sales and it can show a person’s paid intent to travel.
5. A few days later, ARC replied. “Yes, we can confirm that not selling your data includes not selling to any third party, including, but not limited to, any government agency as part of ARC’s Travel Intelligence Program,” the company said…”
