The Daily Mail reports that two British Airways pilots died within days each other, both citing in-flight toxic oil fumes as the cause of their ill-health.

Apparently it's common for pilots to don oxygen masks several times per week during flights due to poor air quality and there are no air quality monitoring systems on British Airways or other airline aircraft.

Before his death, BA Pilot Richard Westgate instructed his lawyers to sue BA for alleged health and safety breaches.

BA Pilot Karen Lysakowska also wrote to BA threatening to take legal action over ongoing air contamination incidents.

British Airways may be liable under the health regulations because they fail to monitor the on-board air quality.

There is no mention of whether passengers are also at risk.
