When Thomas Cook got keen on weight I adapted a jacket I cut the in side of the pocket out and could get 11 tins of ham pushed round to the next pocket in the lining, I walked up to check in like Douglas Bader. After check in it went in my hand luggage, when I went through passport control at Manchester a couple of years ago, they pulled me over asked to open the bag. The girl looked at the tins, I asked if they were ok, she said not a problem but I would strongly advice next time you buy M and S tins of ham much nicer. I always do now, my mate did the same trick with 6 large tins of salmon, only to have them confiscated because they contain more than 100ml of fluid he was gutted.
