China airlines estimate $579 million losses from Boeing 737 Max grounding

China Air Transport Association (CATA) on Friday said it estimated losses at Chinese airlines caused by the grounding of Boeing’s 737 MAX aircraft would reach around 4 billion Yuan ($579.32 million) by the end of June.

China was the first country to ground the 737 MAX two months ago after a crash in Ethiopia killed 157 people in March, in the second such incident for Boeing’s newest aircraft.

“The U.S. air regulator expects approval for the plane to return to service as early as late June,’’ sources told Reuters on Thursday.

Earlier this week, China’s biggest airlines formally asked U.S. plane maker Boeing to compensate them for losses caused by the grounding and delayed deliveries of 737 MAX jets.

“We sincerely hope Boeing will place great importance to the compensation requests made by our member companies and offer solutions in a reasonable and legal manner,” CATA said in a statement on its website.

The association represents 41 Chinese airlines including compensation claimants Air China Ltd, China Eastern Airlines Corp Ltd, and China Southern Airlines Co Ltd.

“We will closely monitor developments and provide proactive and necessary assistance upon request from our member companies, to safeguard their legitimate and lawful rights and interests.

“Chinese airlines had 96 737 MAX jets in operation before the grounding and were due to receive delivery of over 130 more this year.

“As time passes, associated losses will further increase,’’ CATA said.
