Airlines have threatened to take legal action against Heathrow if a settlement is not reached over the costs caused by the airport being shut on Friday.
Airlines are threatening legal action against Heathrow Airport to recoup at least £20 million in losses caused by a Friday shutdown due to a fire at an electricity substation. Despite Heathrow claiming to have handled the situation well, the government has launched an investigation and questions are being raised about the airport's vulnerability to a single point of failure.
