The Canadian government has done a number of things. When the U.S. secure flight program was being contemplated, the U.S. government issued something called a notice of proposed rule-making, which is the process they use as they're moving towards the implementation of a program.
In response to that notice of proposed rule-making, the Canadian government made a number of overtures to the U.S. government. At that time, we sought a full and complete exemption from the entire application of the program. A number of other interventions were made by other countries, as well as other groups, some of which were in the United States.
As a result of Canada's intervention, the U.S. government made a determination that they were willing to give us the domestic exemption—so as you've mentioned, flights between two points within Canada. But at this point, they've been clear that they're not contemplating an exemption for the overflight provisions.
