Can WeChat apply for a green health code by plane?

You can't.

From April 8, 2020, passengers who have purchased air tickets are required to declare their personal data, health status, recent travel and other information through the WeChat micro-flow version of the international health and epidemic prevention code before boarding the plane every day. Special circumstances can be filled in by others.

April 8, 2020 to April 22, 2020 is the transition period. From April 8th, China passengers flying during the transition period should declare daily. Passengers who take flights after the transition period should fill in the Passenger Boarding Registration Form every day from 14 days before boarding. If you fail to fill in the above information, you will not be able to board the plane. Passengers who provide false information will be forbidden to travel and bear corresponding legal responsibilities.
