22/07/2021 Following the launch of the EU Digital COVID Certificate on 1 July, the European Commission has issued guidelines for EU Member States on the best ways to check them before travel, ensuring the smoothest possible experience for air passengers and staff alike. The non-mandatory EU Digital COVID Certificate provides either proof of vaccination, shows if a person holds a negative SARS-COV-2 test result, or has recovered from COVID-19. Therefore, the EU Digital COVID Certificate is essential to support the re-opening of safe travel. As passenger numbers will rise over the summer, an increased number of Certificates will need to be checked. The airline sector is particularly concerned by this since, in July for example, air traffic is expected to reach more than 60% of 2019 levels, and will rise thereafter. Currently, how and how often passenger’s Certificates are checked, depends on the holder’s departure, transit and arrival points. A better-coordinated approach would help avoid congestion at airports and unnecessary stress for passengers and staff.
