Happily, I received another sale notice last weekend. I can now demonstrate the difference between shopping for fares directly from the homepage versus clicking through the sale section or a promotional email alert.

The sale was for 30 per cent off from flights out of select city airports, including Toronto Island Airport — a key location for Air Canada’s competitor, Porter Airlines. I randomly decided to search for tickets to Montreal.
