The Supreme Court has ruled that Air Canada does not have to compensate an Ontario couple who said they were not served in French on international flights.

The court says Lynda and Michel Thibodeau are not entitled to $12,000 the Federal Court said they could get. That decision was subsequently overruled by the Federal Court of Appeal.

The Thibodeaus filed several complaints with the official languages commissioner over the English-only services they say they received from the airline during trips taken between January and May, 2009.

Air Canada previously apologized to the couple.

In its ruling today, the high court noted that the Montreal Convention, a multilateral treaty adopted in 1999, provides for compensation only in cases of death, injury, delays or baggage-related incidents.
