Sure.
There are a couple of things to note. I helped with those IATA recommendations. A lot of those were conjured up in March in Singapore, which was my last trip before everything shut down, so I'm aware of those and I think they're pretty strong because there was broad consultation with the World Health Organization and ICAO as well.
The second thing is that I don't think there's going to be one step to make things safe. It's really a bundle of measures taken together that will make airline travel safer. As I mentioned, I really think we have to focus on the point of origin to the point of destination and everywhere in between. That will really ensure proper safety. Of course, there are only certain things that are under the control of the aviation sector, but if we really focus on a more holistic approach including education, we can make travel safer and instill greater confidence.
Directly related to the plane itself, the air filtration system and ventilation system on the plane are spectacular. If we couple that with universal masking, which is also extremely helpful, and really crowd control as best you can getting on and off the plane while that ventilation system might not be functioning, those are all very high-yield components. Of course, hand hygiene is also important and all the other public health measures that we've been discussing, but those would be the highest yield, in my opinion. Again, it's a bundle.
On the last point, temperature checks, it was really interesting—and don't laugh me off this call—that initially they weren't being done at Canadian airports and everyone said, “Whoa, we're not doing temperature checks. We need to do them.” Then they were doing temperature checks, and everyone was saying, “Whoa, they're useless. We don't need to do them.” It's optics. You're not going to get.... With this infection, you have to have the right fever at the right place and the right time, and there are a lot of optics. I don't think that's bad. It might give some people a little more confidence in travelling, but that in and of itself isn't going to make air travel safe.
