passengers who have undergone plastic surgery must meet the following conditions before they can buy tickets to fly:

1. It has been 15 days since the operation

2. When checking in, they need to produce a medical certificate with the words "suitable for flying" and a medical record to prove the date of the operation.

3. A Diagnostic Certificate filled in by a doctor in a second-class hospital (including second-class hospitals, including clinics, medical centers and hospitals overseas) and stamped with the official seal shall be provided, and the diagnostic certificate shall be issued within 48 hours before the scheduled flight departure.

I hope my answer can help you.
