Paris, Zurich and Frankfurt airports said they had suffered problems with computer systems, but they had been quickly resolved.
Frankfurt airport confirmed in a tweet that Lufthansa and its partner airlines could not check in luggage during a 20 minute period.
Southwest Airlines said it experienced computer troubles at several U.S. airports, while British Airways confirmed that its online check in system had gone down.

"We experienced a network issue that caused disruption to some of our systems," it said in a statement. "As a result of the incident, customers experienced disruption to certain services."
Amadeus said that all systems were working normally by 9:30 am ET.
