The families of four Queenslanders who were aboard missing flight MH370 are suing its operator for hundreds of thousands of dollars, claiming the airline "failed to prevent the flight from being operated in a manner that caused it to crash".
Rodney and Mary Burrows were holidaying with their long-time friends Bob and Cathy Lawton when they boarded the ill-fated Malaysia Airlines flight in Kuala Lumpur, bound for Beijing, in March 2014.
They were among 239 people who perished when the Boeing 777 disappeared.
Documents filed in twin Federal Court cases by relatives and executors of the estates of the Burrows and the Lawtons state that the families are seeking the combined equivalent of nearly A$420,000 from Malaysian Airline System Berhad (MASB), along with "further damages", interest and costs.
MASB was placed into administration in 2015.
