I have. I'm going to go back to CATSA, because I have a number of questions that I want to ask. These are with respect to the user-pay system that we have in Canada for security.
I know there's a difference between what is paid per direction for domestic passengers and what is paid for international passengers. What I want to know is why security for international flights is more expensive than for domestic flights. What's involved in the security for an international flight that causes the cost to go from $7.12 per direction to $24.21 per direction?
