Ken and Airbus320 are right. Paul Brotto, do not try and copy the discount airlines. There is enough competition in the discount travel market already. Instead, work to distinguish Air Canada from the competition. People will pay more for better service, but you have to convince them first that it's worth it. People aren't convinced right now.
(And if Air Canada copies Canada 3000's on-board seating configuration, I will return my Aeroplan card.)
