The deadline for the airline to reach agreement with its pilots is still a week away. But already flyers are scrambling for alternatives and Air Canada is planning to start cancelling flights as soon as this weekend. Tens of thousands of passengers a day may find their flights cancelled, and some may end up stranded far from home. It's happened once already this year. What happens if Air Canada's planes don't fly?

In the bigger picture, this labour dispute is the latest in a series of them that have plagued North American transport all year, from airlines to rail to ports. Why so any, and why now? And what needs to change if we want people and goods to keep moving on time?
