We haven't done any research with that specific kind of question. The Air Rail Link is a unique kind of service, because it's not really positioned as a commuter aid for your trip from home to work and back again. It's more a premium-level service to deliver people to the airport as an alternative to a $50 cab ride.
We actually have a mandate to recover all of our operating costs--and hopefully some of our capital costs--from the fare box on this project, which is quite different from your typical transit service. We're looking at more of a cost-recovery model.
