BERLIN – A German union representing pilots says it is planning a new round of strikes in a long-running dispute over wages and early retirement benefits.

The Vereinigung Cockpit union says in a statement it will order pilots of Germanwings, a subsidiary of Germany’s biggest airline Lufthansa, to go on strike Friday if further negotiations on Thursday fail to achieve their goals.

The union said all Germanwings flights departing from German airports would be affected by the strike Friday from 6 a.m. until noon local time.

Lufthansa spokesman Andreas Bartels said the company regrets that the dispute may affect customers and is considering whether to continue negotiating with the union.

A three-day pilots’ strike in April grounded Lufthansa and its Germanwings and Lufthansa Cargo subsidiaries.
