Technical disruptions slowed down operations at Lufthansa at Frankfurt Airport. A company spokeswoman said that check-in via the airline's website, at the counter and boarding at Frankfurt Airport were affected. There are delays or flight cancellations. Passengers would be offered alternative connections and rebookings on the train.

The technical faults are due to external IT service providers and have existed since Sunday morning. Check-in via mobile browsers, for example on smartphones or tablets, or via the Lufthansa app still works. Lufthansa asked travelers to find out about the status of their own flight. "We are working flat out to find a solution to the problem," said the spokeswoman.

On February 15, a cable damage during construction work in Frankfurt caused Lufthansa's computer systems to fail. The consequences at that time were flight cancellations and delays worldwide.
