1. There will undoubtably be shifts in the route network, but it should be kept in mind that these new aircraft will not be additional capacity to be used for new services. During the period that the new aircraft arrive, it is planned that Air Canada will retire 12 x B737, 2 x A319, 10 x A320 and 7 x B767. Jazz will retire 10 x BAE 146 and 11 x DHC-8 aircraft. Thus most new services will be at the expense of discontinuing others.
2. Assuming domestic capacity will be reduced, I assume Jazz will merely take over the existing RJ transborder routes (mor or less). I do not expect many new routes from that quarter.
3. We can expect that the narrow Airbuses will continue to shift to transborder services, but since there will be fewer of them, some of the EMB-190 aircraft will probably be needed to replace them on their existing routes.
4. I do not expect to see many of the new aircraft out west. Any new transborder routes out west will have to come out of the existing Toronto services and I cannot see that happening very often.
In short, I do not see many route changes before 2008.
Just an opinion.
