Mr. Willie Walsh:

It is a great question. I am pleased to say IATA has a solution for it. We have a system called Timatic, an Irish colleague of mine is heavily involved with running it. Timatic is a central database that includes all requirements for travel - these are typically passport and visa requirements - but it has been extended to include health requirements as well. They can be accessed by airlines. Governments can put in those requirements. In many cases, children will not need to show evidence of vaccination to be able to travel with parents, as has already been stated by several countries. We are developing an app that airlines can integrate into their own apps. People will not have to go to several different sources. An Aer Lingus or even a Ryanair customer using a travel app to check in and fly will have this information. It can all be done through the airline's app. It will demonstrate on departure that a passenger meets all the requirements for entry to the country to which he or she is travelling.

We are engaging with governments around the world and passengers should be able to demonstrate the information indicating they meet requirements on arrival, as well as when they go through immigration. That can be done through one person for the entire family or several people could do it. We have digital solutions either in development or available to us today that will enable people to travel. We are very conscious at IATA that we must facilitate families when they are travelling.
