As I mentioned earlier, an open skies agreement has very few restrictions at all in terms of the rights that foreign and domestic airlines can take advantage of in each other's market. For example, for our open-skies type of agreement with the United States, there's no limit. There are no restrictions on the number of frequencies that Canadian carriers can use to fly into the U.S. market. Those are based on their own commercial decisions, and likewise for the U.S. carriers coming to Canada.
An expanded agreement takes more of a piecemeal approach in which we start at the ground floor and test the market to determine what the market can bear in terms of passenger traffic. As we do our analysis and determine that the market can be expanded because there is interest in additional frequencies, then we would renegotiate the agreement to add frequencies and destinations.
So we add rights on a kind of augmented basis, but we use a gradual approach.
