I would just add to the the issue of cost, tax and fees, in addition to what Mike just said.
In our submission for the CTA review panel, our first principle was that the industry should be acknowledged as an economic enabler and the taxation regime should reflect that. In addition to what Mike stated, we also have in Canada what we call airport rent, which is a fee that the airport has to pay to government and that goes into general revenue. This money is not put back into the system. That represents a significant amount of money. In fact, it was billions over the last years.
What we basically say is that any amount that's taken from the industry should at least be put back into the industry.
