Strikes and staff shortages have already forced airlines including Lufthansa to cancel thousands of flights and caused hours-long queues at major airports, frustrating holidaymakers keen to travel after Covid-19 lockdowns.

The vote does not necessarily mean a strike will be held, but it was a signal to the employer that constructive steps needed to be taken, pilot’s union Vereinigung Cockpit (VC) board member Marcel Groels said.

“We are showing we are ready to talk,” he added.

A spokesperson for Lufthansa said they respected the results of the vote and hoped for a constructive solution at the negotiating table.

Pilots’ union VC is demanding a 5.5% pay rise this year for its pilots and automatic inflation compensation thereafter.

It also wants a uniform pay structure for all staff at the Lufthansa group’s airlines, which include flagship carrier Lufthansa as well as budget unit Eurowings.

Lufthansa has already been rocked by strike action by its ground staff on Wednesday, which forced the carrier to cancel more than 1,000 flights.
