jetset parking advertisement on the Canada Line SkyTrain, Vancouver, BC

The Canada Line is a very popular way for travelers to get to the Vancouver airport. Passengers can walk directly from the terminal to the train. If you have tickets, rather than paying cash, a round trip to downtown is priced at under $10.00.

While there will be lots of people on the heading to airport, is this really a compelling message? Is the complexity of parking really what keeps potential customers from using jetset's services? Or is it the price?

Or are the people who travel on the SkyTrain not part of the driving public? I'm not convinced that this campaign, highly targeted though it is, will be effective.
