Dutch national carrier KLM said it scrapped 28 round-trip flights Monday across Europe after ground staff downed tools in a two-hour strike for higher wages.
Airline spokeswoman Manel Vrijenhoek said the move came after a section of ground crew belonging to the largest Dutch union federation FNV stopped work from 8:00 am to 10:00 am (0600 GMT to 0800 GMT).
"We announced yesterday that 11 return flights will be preventively cancelled with a decision to scrap another 17 today," Vrijenhoek told AFP.
"Our operations in the meantime have started up again with a delay of about half-an-hour," she said.
The FNV said Saturday it was demanding a four percent increase for some 15,000 ground staff, with KLM's latest offer stalling at two percent over the next three years, with three percent offered in the first year.
