Life gets even more fun when you receive the 'I.D' - it looks like something a 12 year old could make with Microsoft Paint, the harps are green on mine.... incredible. I was refused airside access at a UK base with the Ryanair 'I.D' because it "isn't a proper airside pass" upon my insistence that the company told me it was, I was promptly laughed at. It seems to work fine in Spain, however I suspect you could get airside at many Spanish airports by waving your Blockbusters card at them.
