In the time in between peak travel windows, the problems at Canada's major airports seem to have mostly vanished. But does that mean airlines and airport authorities have actually fixed the issues that had us ranked among the worst in the world last year? Not really.

The massive numbers of cancelled or delayed flights, and the chaotic snapshots of hundreds of bags scattered about are primed for a comeback, because there's an underlying problem we haven't solved. And there are lessons even a year of awful press has not helped the industry learn. So what makes Canada's airports and flights so unstable? What could have been done to fix this? And will it really take no more than a busy week or a bad storm to send this country's air travel into a tailspin?
