Cancelled flights of German airline Lufthansa are displayed on a schedule board during strike action by Lufthansa pilots at Fraport airport in Frankfurt April 3, 2014. Lufthansa pilots were on strike for a second day on Thursday, grounding Germany's largest airline in a row over retirement conditions. The pilots announced a three-day stoppage earlier this week, leading Lufthansa to cancel 3,800 flights, or around nine out of ten flights planned for the period.
