Right. As I mentioned in my opening remarks, there has been a confluence of factors. Of course, as we're noting, the labour shortage across the sector has been a significant challenge for airports and air service operators, and I think that is something that is staying with us.
Despite those challenges, we are working hard to figure out how to best address the shortages, but we also see other challenges in the system, such as a greater concentration of flights at certain times of the day, and delays in parts of the system, including overseas, which have an impact here in Canada. We see customs pre-clearance. We see different passenger patterns, such as more carry-on luggage. We also see weather conspiring against us at exactly the wrong times as well, as it will do.
All of these things create this situation where there's a knock-on effect, and we need to make sure we understand what is driving the issues at a given moment in time. That allows us to tackle those issues head-on. I think having this collaborative forum through which we're working together is helping us to do exactly that.
