If you're a frequent flyer or shop in bargain basements, your credit card info may have been compromised.

Delta Air Lines Inc. and Sears Holding Corp. announced on Wednesday they were affected by a cybersecurity breach at the software company they both use called [24]7.ai.

The awkwardly named software company informed Delta and Sears on March 28 that a breach occurred from Sept. 26 to Oct. 12, 2017. It reportedly affected customer payment information.

Sears says that under 100,000 customers have been affected, and that the breach includes Kmart shoppers.

Delta has confirmed that no other information, such as the passport or other government ID info, was compromised. However, the investigation into the extent of the breach is ongoing.

"At this point, even though only a small subset of our customers would have been exposed, we cannot say definitively whether any of our customers' information was actually accessed or subsequently compromised," Delta said in a statement.

Sears is also continuing its investigation, and working to let affected customers know about the breach as it learns more.

"Our top priority at this point is to quickly identify the impacted customers, notify and assist them in every way possible," Sears said in a statement.

Data breaches have become all too familiar to anyone who uses a credit card, shops at a store, or just freaking lives in the world. The 2017 Equifax hack affected millions of users. But as Mashable's MJ Franklin reported, many of the world's biggest retail and food chains, including Target, Whole Foods, Wendy's, and more, have been compromised in recent years.
