In a bid to make it easier for passengers to make trips, the International Air Transport Association and airlines such as Ryanair and British Airways are looking to introduce new travel pass apps that would carry information about an individual’s Covid tests and vaccination status. The aim is to allow technology to simplify meeting the complex travel requirements still in place, but some have expressed concerns that these threaten privacy and could discriminate against those who are not vaccinated. In any case, questions remain as to whether there will ever be consistency in government Covid requirements around the world.
