We're constantly reassessing the measures that we have put in place from a health point of view, and we're adapting them as we go along based on the latest health guidance that we get. Depending on how the pandemic plays out over the weeks and months to come, and how, for example, a vaccine testing regime is implemented, we may be able to move away from some of these measures as new measures come into place or as the pandemic comes under control, but I think the bottom line is that we have the flexibility to adapt to changing health conditions and respond to the changing health advice.
A good example is how our requirements around face masks have evolved over time. We have adjusted them from the initial requirements in the spring to more recent requirements based on the latest health guidance that has provided more flexibility for parents travelling with younger children when using face masks.
We will evolve over time based on the latest information.
