BEIJING—China Eastern Airlines has started putting its Boeing 737-800 jetliners back in use for commercial flights less than a month since a crash killed 132 people and led the company to ground 223 of the aircraft, the carrier said on Sunday.
The airline said it had conducted systematic tests, structural checkups, and verified airworthiness data for each of the aircraft, and that test flights would be carried out on all planes before they resumed commercial services.
