FRANKFURT (dpa-AFX) - The announced warning strike by Lufthansa ground staff at Frankfurt Airport began on Wednesday morning. A Fraport spokeswoman said this morning that 90 percent of Lufthansa's flights were expected to be canceled. "We have an extremely high level of willingness to strike," said a Verdi spokesperson. The union assumes that Lufthansa will probably also not be able to carry out the fuselage flight schedule as planned.

Together with Munich, Germany's largest airport will be the hardest hit by the strike planned for 27 hours. In Frankfurt, 80 to 90 percent of the approximately 600 planned take-offs and landings of the Lufthansa core brand and the Group's own feeder airline Air Dolomiti had already been canceled in advance. However, the other Group companies and external airlines are still flying.

If domestic flights are canceled, customers can switch to rail travel with their flight tickets. Passengers on canceled flights should not come to the airport under any circumstances, Lufthansa warned. They could not expect any help there. "Due to the strike, the rebooking counters are unfortunately not staffed," the airline's website stated. Free rebooking options were available via, the customer app and the service center.

Verdi has called on employees at various Lufthansa companies in Frankfurt am Main, Munich, Hamburg, Berlin and Düsseldorf to go on warning strike. As a precaution, the airline has canceled between 80 and 90 percent of its 1,000 scheduled flights for Wednesday. More than 100,000 passengers had to reschedule.

In the current wage dispute, Verdi is demanding 12.5 percent more pay, but at least 500 euros per month for a period of twelve months. In addition, there is to be a uniform Group-wide inflation compensation bonus of 3,000 euros. Lufthansa refers to past wage increases and has offered 13 percent more pay and an inflation compensation bonus for a period of three years. The next round of negotiations is scheduled for February 12 in Frankfurt am Main /osf/DP/mis
