In a hugely pioneering initiative, Hong Kong International Airport (HKIA) has successfully conducted the trial of digital health passes on a flight between Hong Kong and Los Angeles. Designed to provide a simple and efficient means of checking and verifying health documents at both ends of a passenger journey, the trial was conducted in conjunction with Los Angeles International Airport (LAX), Cathay Pacific, The Commons Project, one of the major digital health pass developers for international travel, and Prenetics, a COVID-19 test provider.
