Well it is more than that I think.
I don't see how we can possibly ask anyone to opt-in before any cookies have been set.
It seams to me that the best we could be expected to do is have a prominent link to a page where they can then click a link to remove those cookies already set.
I liked the way that airline then took you to page which then gave an opt-in - saying that was the only way you could use the site anyway.
