Amid heightening US-China trade anxieties, three of the largest airlines in China have requested Boeing to compensate losses incurred by the companies for grounding and delayed deliveries of 737 MAX aircraft.

According to reports in Chinese media, China Eastern Airlines Corp Ltd, Air China Ltd and China Southern Airlines Co Ltd have requested for compensation after their businesses suffered. China was the first country in the world to ground 737 MAX after an air crash in Ethiopia in March which resulted in the loss of 157 lives.

The US Federal Aviation Administration (FAA) is due to host global regulators on Thursday in Dallas to conduct a review of Boeing’s 737 MAX software and training proposals. Following this meeting, the FAA will take a call on whether or not to end the grounding and by when these aircraft can fly again.

Other international airlines including Flydubai, Turkish Airlines, Ryanair and United Airlines have also requested Boeing for compensation over 737 MAX grounding.
