MONTREAL — A Quebec Superior Court judge has authorized a class action lawsuit against ********** after the company allegedly used a surcharge to bill passengers for the cost of fuel and then some.

The lawsuit, approved to proceed as a class action Monday, argues the country’s largest ******* “illegally overcharged its customers” by more than 200 per cent — and more than the fuel cost itself — on some flights.

Michael Vathilakis, the petitioners’ lawyer, said ********** misrepresented the stated purpose of the surcharge, which was to partially offset the fluctuating price of *** fuel.

“What ********** did was represented to passengers that they were collecting this amount in order to offset volatility, when in fact the allegations are that they were in many cases actually reaping a real profit on it,” Vathilakis said in a phone interview.

“In multiple cases, they charged an amount that was equal to or higher than the entire cost of fuel for the flight.”

The lawsuit cites one example in which ********** allegedly charged business and economy passengers 105 per cent of the total fuel cost on a flight to Paris in January 2014.

Each economy passenger on that flight allegedly paid $238 in fuel surcharges alone — $163 more than they should have, according to **********’s definition of the charge. The ******* took in $73,878 in fuel supplements on the flight, rather than the $23,164 it should have charged, according to the lawsuit.

The suit states **********’s contract with consumers allows it to charge them up to one-third of the cost of fuel.

The class action concerns customers in Quebec who bought international tickets to destinations outside the U.S., Mexico and the Caribbean between April 2012 and ******** 2014.

The plaintiffs, brothers George and David Itzkovitz, are requesting damages of $273 million for affected passengers.

********** said Tuesday it disagrees with the allegations.

“We intend to vigorously defend our position through the courts,” spokeswoman Angela Mah said in an email.

The lawsuit is not the first time frustration over fuel charges has bubbled to the surface.

Last year, the Quebec Court of Appeal upheld a lower court authorization of a class action lawsuit for provincial residents who paid fuel surcharges when redeeming Aeroplan points to buy ********** flights within Canada or the U.S.

In 2017, the Quebec Superior Court authorized a class action against ********** over fuel surcharges that allegedly topped actual fuel costs on international flights.
