If a restaurant advertises a "Champagne Bunch", do you expect champagne to be served? What if the restaurant's "champagne" is sparkling wine, would you feel disappointed, let down, tricked?

That basically is the class action complaint against Sunwing Airlines. Sunwing advertised "Champagne Service" which included a "complimentary on-board champagne toast". But instead of champagne, pax Daniel Macduff was served a "cheaper bubbly". Mr. Macduff was let down to say the least and filed a class action suit that alleges "misleading marketing" and demanding compensation for the difference in the wines prices. Sunwing for their part believe the lawsuit to be "frivolous and without merit".

So, the question is...Is it "champagne service" if it's sparking wine in a cup?
