Every month, an airline printed advertisement, minus airline name and logo, is displayed for your guessing pleasure on Guess The Airline. The following is the answer to a previous game.
This was a different Guess The Airline, in the sense that it was not an actual airline advertisement, but rather an RBC Royal Bank Visa advertisement, promoting a credit card affiliated to a now defunct frequent flyer program in Canada. It was published on the airline’s inflight magazine issue of July 1999. Ready? Scroll down!

How to guess it?
The introductory text mentioned this was a Canadian frequent flyer program back in 1999. Air Canada already had a long-date affiliation with CIBC Visa as well as Diners Club (and later on, with American Express). The only remaining Canadian airline having a frequent flyer program affiliated to a credit card was Canadian Airlines. The word “Plus” in the phone number could have also been a clue.
