Given that the security programs and requirements have all been driven by the governments, whether in the case of passports, NEXUS cards, or enhanced driver's licences—those types of things—there's nothing I'm aware of that has been widely circulated within the public concerning people's willingness to give it up. But I think, based on our experience of seeing passengers work through the various processes, there is a willingness to give up a certain amount of personal information if there is a corresponding reassurance that the information will be treated with ultimate discretion by the authorities who get the information and by those private companies who receive the numbers afterwards. If, for example, we're trusted with passport information from all of our passengers who travel internationally, we have to treat that information with the ultimate in discretion, and passengers depend on us to be doing that.
To your point about enhancing cards and using that information, if more information were going to be passed to the carriers, we would have to treat it with discretion, but we would also request that there be consistency in the formats. Each province has a different format for their driver's licence number, and that's a nightmare for us, for systems. And then the passports are different. From a carrier perspective, to be able to capture that information, if those types of programs were to be put in place, and then effectively use it would become extremely expensive and difficult for us, unless standards were put in place right from the beginning.
So while we support those types of programs and that type of discussion coming forward, it has to respect the public's need for privacy and for control of information. It also has to be put in such a way that it can be used in an economically viable manner by the companies involved.
