Some passport numbers were among the details accessed. Which airlines are hit and what to watch for. - Author: Zach Benitez - Tags: News, Breaking News, #live The Amadeus data breach is turning into a story about more than one airline. Japan Airlines, ANA, Korean Air and its subsidiary Asiana have all said in the past week that someone accessed passenger booking data through Amadeus, the Spanish technology company whose systems run reservations, ticketing and check-in for many of the world's airlines. Japan Airlines says about 92,000 of its customers were affected, and for about 2,000 of them, the exposed details included passport numbers. Investigators are still working out whether other airlines were affected too. --- ## Latest Updates **Friday, Oct. 30, 4:45 p.m. ET:** ANA has reportedly put a number on it: about 37,800 passenger records were involved. German leisure airline Condor has also reportedly confirmed it was affected, which would bring the count to seven. The access ran from August 2023 to September 2026, according to Cathay Pacific, more than three years before anyone noticed. Amadeus still hasn’t said how many of its airline customers were hit. **Thursday, Oct. 29, 9:45 a.m. ET:** ANA said Thursday that customers' personal information may have been leaked after unauthorized access at one of its contractors, identified as Amadeus. It hasn't said how many customers or what information is involved, and it's still investigating. ANA's regional partner StarFlyer has reportedly said its bookings were viewed as well. We'll update this page as more airlines respond. --- ## What Was Exposed Japan Airlines has given the most detail so far. Amadeus told JAL on Oct. 23 that it had found signs of outside access to reservation data, with traces going back as far as August 2023 and running until late September this year. For about 90,000 customers of JAL and its subsidiary Japan Transocean Air, the exposed information was the booking code, name, flight date, route and cabin. For about 2,000 more, it also included email addresses, phone numbers, passport numbers, nationality, frequent flyer numbers and ticket and seat details. JAL says no credit card numbers or passwords were exposed, and Amadeus says it has found no evidence that the information has been misused. Flights aren't affected. Korean Air and Asiana were notified a few days earlier, on Oct. 20, and say booking numbers for some customers were accessed. Their investigation points to someone using login details belonging to an Amadeus system account, rather than breaking in some other way. ## Know Before You Fly Breaches, scams and disruptions that could affect your trip, explained in plain English.

That's what makes this breach worth watching. So far, only these airlines have said they were affected, and Amadeus hasn't said whether anyone else was. If more airlines come forward, the number of travelers involved could grow quickly. --- ## What to Do Now If you've booked with Japan Airlines, ANA, Korean Air or Asiana in the past few years, the biggest risk right now is scams rather than stolen money. Someone with your name, booking code and flight details can write a very convincing fake email or text, pretending to be your airline and asking you to "confirm" a booking, pay a fee or claim a refund. - Don't click links in unexpected messages about your booking. Open the airline's app or type its website address yourself instead. - Be wary of anyone calling about your flight and asking for card details or a passport number. - Turn on alerts for your frequent flyer account and check its activity, since some frequent flyer numbers were exposed. - If your passport number was exposed and you're worried, you can contact your country's passport office for advice, though a passport number alone usually isn't enough to steal an identity. JAL says it will contact affected customers directly and has opened a dedicated help line, at +81-3-4332-7280 from outside Japan, on weekdays from 10 a.m. to 5 p.m. Japan time.
