I flew out of T5 and had the form folded in four in the back pocket of my jeans, I was asked twice at the first wing if I had it , once at the podium and once at check in. I replied "yes" both times, reached around to my pocket but the offer to show was waved away before my hand touched the paperwork. It was still the when I arrived into GIB and nobody else laid eyes on it.
There were no police or other officials asking questions in the Terminal however I was on a 07:15 departure.
