British Airways has started a two-day strike, almost all fights have been grounded and thousands of passengers were disrupted in a dispute over pay.
The airline is part of the International Aviation Group (IAG), which canceled 1,700 flights to and from London Heathrow and Gatwick airports on Monday and Tuesday before British Airways first ever pilot strike.
Australians who travel on Qantas codeshare flights across Europe are also mostly to be impacted by the industrial action.
A further strike is scheduled on 27th September.
