Pilots at Lufthansa’s budget airline, Germanwings, started a two-day strike on Thursday as German pilots’ union Vereinigung Cockpit (VC) seeks to put pressure on management in a long-running row over pay and conditions. The VC pilots staged 10 strikes last year, affecting hundreds of thousands of passengers and wiping up to 200 million euros ($226 million) from 2014 operating profit at Lufthansa, which is trying to reduce costs to keep up with rivals.
