The dust has been settled for a few days as far as the reopening of Mainland of China is concerned. Has anyone on FT flown to China since Jan 8? I am interested in knowing the Checkin and boarding process, in particular, regarding the COVID test certificate. I know that the WeChat mini-program from Customs of China does not require uploading of the PCR test certificate. Does CX check the certificate at all at either checkin or at gate after one shows the green code? Thanks.
