Some American Airlines customers, employees' personal information exposed in data breach

Major carrier American Airlines said Tuesday the personal information of "a very small number of customers and employees" were exposed during a data breach earlier this summer. 

"American Airlines is aware of a phishing campaign that led to the unauthorized access to a limited number of team member mailboxes," American Airlines told FOX Business. 

However, it noted that only "a very small number of customers and employees’ personal information was contained in those email accounts."

The information that was exposed may have included names, birthdates, mailing addresses, phone numbers, driver's license and passport numbers, as well as certain medical information, according to a notice of incident from the carrier, which was issued last week. 
 

So far, the airline said it has "no evidence" that the personal information was misused, but it is still offering affected team members and customers "precautionary support." This includes two years of identity theft protection coverage with Experian.
