We feel for Nav Canada employees and everyone in our sector who's hurting. That's why we've been pushing the government to resolve their financial issues.
On the specific element of your question, we fly to airports that have towers and airports that don't. We fly to airports that have towers part of the day, and not other parts of the day, so it's not a straight line.
Also, with respect to the safety of those decisions, that is between Nav Canada and their regulator, but we're aware of the situation in Regina, and feel for those employees, for sure.
