Sept. 28 (UPI) -- A passenger and baggage check-in software problem resulted in brief delays in some of the world's busiest airports on Thursday.
Madrid-based Amadeus IT Group reported its Amadeus Altea software was hit with a network issue, disrupting some of its systems. Check-in processes in airports around the world were delayed and in some cases, boarding passes were issued manually.
A company statement said technical teams quickly identified the cause of the problem, adding that services are "gradually being restored."
Stephen Moynihan, spokesman for the Australian airline Qantas, said, "Amadeus, a check-in system for passengers, went down and now has come back up. Check-in was resumed quite quickly."
Dublin's airport reported the system was down for 12 minutes. The airport of Manchester, England, reported a 15-minute delay.
Among airports reporting a problem were Zurich, Frankfurt, Incheon in Seoul, Haneda in Tokyo, Charles de Gaulle in Paris, Changi in Singapore, Reagan National Airport in Washington, D.C., and Gatwick and Heathrow airports in London.
Airlines reporting problems included Air France, Southwest, China Air, Qantas, Korean Air and Lufthansa.
