I flew a couple a months ago and the peg was not noticed at all and I just put the jevity in my checked luggage. Thanks for the heads up though, I will just go hungry if I take a longer trip rather than try to carry it on. I don't understand making you pour it down the tube, did they think it was poison? I've never heard of a plane being highjacked with poison. I do have a question though, I am never hungry or full, in fact I must put five cans on the counter every morning I would forgot I had any, or used enough. Do you get hungry?
