I can speak to some of the travel impacts we've seen in other jurisdictions. It is very fluid. Countries have introduced different travel restrictions. For example, we know that some airports in the United States, in key hubs, were only down as much as 50% to 70%. We know that in other jurisdictions there hasn't been a great propensity to travel.
However, we are down significantly. We spent the first period of time down more than 90%, year over year, in certain months. It continues to be a significant challenge for us to get a footing. As we deal with ongoing travel restrictions and changes and screening requirements, we're going to continue to see changes and impacts on our passenger numbers.
I'm looking at my colleague, Ian, in case he has any additional information.
