ANA investigates possible customer data exposure through contractor
ANA says unauthorized access may have exposed customer information linked to its flight bookings in Japan.
The access occurred at Amadeus, a Spanish company that provides ANA’s passenger service system, which handles reservations and other travel processes.
ANA said there are signs that a third party viewed some customers’ personal information, but it has not identified the number of people affected or the data involved.
The same company’s system was also linked to a recent incident at Japan Airlines, which said about 92,000 booking records may have been accessed.
That incident included passport numbers and contact details for about 2,000 people, according to JAL’s announcement.
ANA is working with Amadeus to establish the impact and says it will notify affected customers when it has more details.
