My last question is for Mr. McKenna, from the Air Transport Association of Canada.
By the way, I miss flying. I might be one of the few people in Canada who misses flying and would go on a plane tomorrow if I thought it was safe.
I want to continue a little with the line of questioning around regaining passenger confidence. In places such as Hong Kong, and maybe Taiwan, as soon as you arrive at an airport, they do testing. You have to wait until the testing is done. Then there's an app that you have to download, and you have to follow up for 14 days as you quarantine.
Would you recommend something such as that for Canada to be looking at, or a version of that, or are you seeing different systems around the world that you might want to draw our attention to, which might actually increase our passenger confidence?
