Air Canada latest airline to suffer disruptions from computer glitch

Air Canada saw its operations disrupted by a computer glitch Tuesday that resulted in delayed flights and cancellations. The airline said the IT system hardware problem was resolved by the afternoon, but not before it caused problems at airports and online. Several Air Canada flights departing from its hub at Toronto's Pearson International and Montreal's Trudeau International were cancelled. On its website, the airline said some of the flights were affected by adverse weather including freezing rain.
