TORONTO: Air Canada says a computer glitch resulted in a temporary mispricing of West Coast flight passes for business class travel after customers bought the passes at a significantly reduced price. Air Canada Spokesman Peter Fitzpatrick said on Friday that the pass, good for 10 one-way flights, was displayed at $604 earlier this week instead of the correct price of $6,048. He says when the airline became aware of the error on Wednesday, the passes were removed from the system. Customers saw the offer on a Facebook travel group page. Air Canada was not able to say how many passes were purchased. The airline says it is contacting purchasers to apologise and provide a refund.
