It is challenging, because there are many factors at play. Of course, there are factors at play in arriving at the airport and being ready to be screened and getting through screening in time for your flight. There are also factors in terms of aircraft arriving and the process by which, particularly internationally, you're coming back into Canada.
Exactly on this challenge, the communications aspect of what we're working together on is something we've been addressing to get better communications amongst partners. That way, when we're communicating about what travellers can expect in terms of managing delays and how they'll get through screening or other border measures, it's clear, it's consistent, it's in time and it's messaged by all partners in the system. No matter where that traveller might be, the information's available to them to make the choices they need to make in order to have more efficient travel through the system.
