(Consumerist) - Sure, you may have a preference when it comes to ordering fancy drinks on a flight, but would you be ticked off enough to sue over bubbly that is not actually Champagne?

A man who flew on a Sunwing Airline flight from Quebec to Cuba last year says he was expecting an advertised complimentary “champagne service” as part of his travel package, but that instead of receiving a glass of bubbles from France’s Champagne region, he was served another kind of cheaper sparkling wine, reports The National Post.

He’s now filed a lawsuit seeking class-action certification demanding compensation for the difference in cost of the beverage as well as punitive damages.

This incident — which only happened on one leg of his flight — apparently popped his cork not because he’s snobby, but because he claims Sunwing’s advertising was misleading.
