Certainly, a lot of the technology that we have and the kiosks that are in place are new, so some of the familiarity with how to use the systems will come with time. There is an educational component to this. I would say it's an ongoing effort with CBSA. You're seeing kiosks being put further downstream or upstream, in terms of being closer to the gate and further away from the customs hall. That's helping.
We have a tremendously valuable forum with Transport Canada called the air consultative committee, where CBSA, Citizenship and Immigration, and Transport Canada work together. All of these agencies have a role in the process. It's amazingly complex how the responsibilities for this traffic flow really kind of align.
A lot of that work is happening, and the educational work is happening. The way the technology itself works is improving. For the primary inspection kiosks that are in place, there are some issues with the transaction times, so we're working with CBSA on how to make that move a little bit better. That's a work in progress.
Can you remind me of the second part of your question?
