When Air Canada pilots went on strike in September 1998 for 13 days, all of the carrier's more than 600 daily flights were grounded, stranding passengers and costing the airline C$133m ($96m; £71m) before a deal was reached.

Air Canada has suspended all operations as more than 10,000 Air Canada flight attendants went on strike early Saturday after a deadline to reach a deal had passed, leaving its 130,000 daily customers scrambling during the peak summer travel season.
