More than 1,000 flights could be disrupted today as workers strike at Frankfurt airport.
And trade union GdF is calling for another day of walkouts on Friday from the marshalling staff – airport workers who guide planes in and out, reports Reuters.
Lufthansa has cancelled nearly 100 flights including its London to Frankfurt service.
Its website said: "Lufthansa regrets any inconvenience to Lufthansa passengers caused by the threatened strike measures by the GdF union and will do its utmost to minimise impacts on passengers. Passenger support and service has paramount priority."
British Airways has also said its services to Frankfurt may be affected.
The walkout comes after the union failed to reach a wage agreement for the workers with airport operator Fraport .
Fraport has trained additional staff to replace workers going on strike and hopes that at least half of scheduled flights will take place during the walkout.
GdF has said that the workers’ pay needed to reflect extra complexity resulting from the recent opening of a fourth runway at the airport. Fraport, meanwhile, has said GdF’s demands are too high.
