London's largest airport, Heathrow, is threatened by a strike this week, Sky News reports.

The background is that the employees in the fuel filling department have said no to a revised salary proposal, according to the trade union Union.

As it stands now, the strike will begin on Thursday and continue until Sunday, with hundreds of flights expected to be delayed.

The employees work within Aviation Fuel Services, ATS, which handles fueling for over 70 airlines, including Virgin Atlantic, American Airlines, United, Air France, Delta and KLM.
