A B.C. law firm has filed a proposed class action lawsuit over Air Canada’s discount ticket debacle last month.

Munroe & Company alleges the airline broke consumer protection laws after it sold pricey business class packages at an enormous discount then refused to honour them.

“After repossessing the flight passes, Air Canada deleted information from its website and misrepresented its contractual rights to consumers,” the law firm said in its summary of action.

Customers flocked to the Air Canada website in late August after it was discovered the airline was selling 10-leg Western Canada flight passes for just $800 – a 90 per cent discount from the usual cost of $8,000.

Air Canada blamed the pricing on a computer glitch and apologized, but said it would not be honouring the flight credits, save for ones that had already been booked.

Munroe & Company alleges after the error was discovered, Air Canada also removed a section of its Frequently Asked Questions web page that promised flight pass prices are “guaranteed.”

The firm said it has filed similar suits in both B.C. Supreme Court and the Supreme Court of Quebec.

If the suit is certified as a class action, people who purchased the discounted flight passes may be automatically included as class members, Munroe & Company said.
