Yes, that was was a relevant consideration in our two most recent reviews.
Just to remind you again, in a merger review we're looking at competition on specific OD pairs. In the Air Canada and the WestJet reviews, it was competition for vacation packages, not just the flight. In the context of those reviews, we looked at OD pairs and whether border airports might be substitutes for passengers. The evidence that we collected indicated that there would have to be a large price differential before a passenger would incur the time and the added transportation costs to substitute a way to a border airport.
