How to guess it?
It was quite easy to guess this ad, originally, if you looked at the following clues. The country: Canada. Already, it shrinks the number of airlines. And then, the year: 2003. It immediately eliminates most airlines, including short-lived Roots Air. And Air Canada? It's been around for much longer than 15 years. What about Canada 3000. Had it survived the September 11, 2001 attacks, it would have indeed been 15 years old in 2003. So, who's left, and who offers "Club Class"? This airline.A special thanks once again to my friend Pedro R. for taking care of evaluating the answers during my trip to Europe, symbolically illustrated by this advertisement. Only difference is that this time, I flew another airline.
