Ms Oonagh Buckley:

I cannot really say how they got through. We are obviously not standing over boarding procedures at airports in other countries. I should say that even from our experience of the digital Covid certificate in the period of greater travel over the past few months there would often have been one or two cases. People do manage to get through. There could have been oversight. It is not necessarily deliberate - it is just that people are rushing or busy. I would not necessarily say that there is anything particularly malign about it in that regard. Similarly, we occasionally get people getting through who require a visa. The visa requirements are long-standing and all airlines know them but occasionally people manage to bypass the system, for whatever reason.
