Qantas says a "technology issue" in its app that allowed some users to see others’ profiles and booking data was likely introduced during "recent system changes".
Users on X reported being logged in as “a different person each time” the app was opened.
One showed that refreshing the app on their smartphone displayed someone else’s account, before reverting back on the next refresh.
“I have access to the booking details, QFF numbers, status, and boarding passes of people I don’t know,” X user lachlanlawyer tweeted.
The issues were similarly reported by users on frequent flyer forums, though not all were able to replicate it.
Qantas said in a statement that the issue "was isolated to the Qantas app with some frequent flyers able to see the travel information of other customers, including name, upcoming flight details, points balance and status."
"No further personal or financial information was shared, and customers would not have been able to transfer or use the Qantas Points of other frequent flyers," the airline said.
"We’re not aware of any customers travelling with incorrect boarding passes."
Qantas said there was "no indication of a cyber security incident" as being the cause. However, the app issue may be considered a privacy breach due to the way it manifested.
The airline had earlier recommended that customers "log out and log in" to the Qantas App to try to correct the issue.
