German flag-carrier Lufthansa has been forced to cancel flights on Friday as cabin crew continue industrial action.
Strikes last Friday and on Tuesday this week saw hundreds of flights grounded, mainly at Frankfurt Airport, as members of the UFO union walked out in a dispute over pay.
Action will again be taken at Germany’s three busiest airports - Frankfurt, Berlin and Munich – on Friday.
Lufthansa has cancelled short and medium-haul flights but also services to and from Shanghai, Jakarta, Seattle and Los Angeles.
UFO members are calling for a five per cent increase in pay after three years of stagnant wages.
Lufthansa has offered 3.5 per cent, tied to changes in working conditions.
Lufthansa is currently undergoing a 1.5bn euro (£1.2bn) cost-cutting programme to offset rising fuel costs and tackle competition from low-cost and Gulf carriers.
