After construction work damaged broadband connections at Frankfurt airport and caused check-in and boarding problems for Lufthansa, the airport made the decision to cancel more than 200 flights.
However, the airline reported that all of its systems had been brought back online.
Earlier on Wednesday, planes were either canceled or delayed, leaving thousands of people stuck throughout the world.
The airline anticipates a restoration to normal operations for planes departing from Frankfurt on Thursday.
On Tuesday, the business reported that engineering operations being performed on a railway line in Frankfurt accidentally severed a bundle of cables.
It has suggested to customers who are going on domestic flights that they purchase train tickets instead, and it has informed consumers that they can get a refund through its website.
In a tweet, Lufthansa said that the company was “working on a solution fast.”
According to the data provided by the website FlightAware, which monitors the status of aircraft throughout the world, more than one hundred planes have been delayed.
According to the accounts of several passengers on social media platforms, the German airline had resorted to utilizing pen and paper to organize boarding procedures and was unable to digitally process baggage.
One passenger reported that the staff at Frankfurt airport was only assisting people who were manually checking in.
“Before arriving at the airport, affected travellers are encouraged by Lufthansa to check the status of their flight via the airline’s mobile app or website before continuing on their journey. Until Sunday, passengers on domestic flights have the option of switching to Deutsche Bahn “according to a statement issued by the airline.
A representative of the company said in an additional statement, “We regret the trouble this will cause our guests.”
Flights departing from Frankfurt Airport, which is the busiest airport in Germany, have been rerouted by air traffic controllers; however, the situation has affected services all over the world.
The failure was attributed to a drill that had cut through a bundle of fiber optic cables owned by Deutsche Telekom, according to Lufthansa and Germany’s national train operator.
Because of this, Lufthansa’s passenger check-in and boarding systems froze up on Wednesday, which led German air traffic control to postpone inbound planes.
Since then, however, these have resumed, and there have been approximately 40 landings per hour at Frankfurt airport since lunchtime on Wednesday. This is practically normal traffic, according to Germany’s DFS air traffic controllers.
In a statement, Deutsche Telekom said, “Two cables have already been restored by our technical team overnight, and many customers are already back online.”
In a separate development, employees at German airports are planning to go on strike this coming Friday over a disagreement regarding their pay.
A month ago, all flights within the United States were halted because a contractor accidentally destroyed files from an essential computer server that was utilized by pilots.
The Notice to Air Missions (Notam) system experienced an outage on January 11, which resulted in the cancellation or delay of at least 1,300 flights and the postponement of more than 11,000 others.
