KLM cancelled dozens of flights on Monday after ground staff at Amsterdam's Schiphol airport staged a two-hour strike in a dispute over pay.
The strike was called after a deadline to reach a new pay agreement between the airline and the trade union expired on Friday.
The union’s demands include an 8 per cent pay rise spread over two years, more full-time contracts and a more regular shift rota.
On Thursday, KLM offered a 6-7 per cent pay rise over three years, which the unions rejected.
