A man checks in at a Lufthansa counter at the airport in Munich, Germany, 20 October 2014. Lufthansa long-haul pilots announced they would be joining part of the industrial action planned by their short- and medium-haul colleagues over changes to their retirement plans. The long-haul pilots would walk out from 6am (0400 GMT) on 21 October to 11.59 pm, the Cockpit union said. Short- and medium-haul pilots said on October 19 they would stop work from 1pm (1100 GMT) October 20 until 11.59pm October 21. Long-haul services affected would include all Lufthansa flights on Airbus A380, A340 and A330 planes, as well as any national flights on Boeing 747s, the union said. Andreas Gebert / EPA

The strike is the eighth this year by the Cockpit Union, which is fighting to preserve an early-retirement scheme that allow pilots to leave after 55 on generous benefits.
