A strike by Lufthansa pilots that has already grounded thousands of flights has been extended until tomorrow (Friday).
More than 215,000 passengers have been affected after pilots first walked out last night.
Around 1,800 flights yesterday and today have been cancelled.
The German carrier condemned the Vereinigung Cockpit (VC) union for extending the industrial action into a third day.
All short haul and medium haul flights within Germany and Europe will be affected tomorrow, the carrier warned.
“Lufthansa notes that, for completely incomprehensible reasons, pilots’ union Vereinigung Cockpit has already announced their next walkout during their current strike,” the airline said.
“The call to strike was announced for Friday, November 25, between 00:01 and 23:59.
“The third consecutive day of strikes will once more hurt business travellers, tourists and commuters.
“Lufthansa is therefore appealing to Vereinigung Cockpit once more to accept the offer of mediation and return to the bargaining table. It is the only place where a compromise can be reached.”
The airline pledged to run all long haul flights from the hubs in Frankfurt and Munich as scheduled.
A special flight schedule for Friday is due to be finalised by midday today.
