Indeed. Worked well in Montreal (where it was also the initial idea), didn't it ... or not
In fact the Montreal split between International and Domestic (which includes USA) was said to be behind airlines deserting Montreal for Toronto as their principal Canadian entry point, and in turn contributing to Montreal's decline as the principal Canadian commercial centre. Later reversed, and the new Mirabel closed, but by then it was too late.
