I know that a gun permit is needed to fly through Amsterdam. My question is regarding if I need to affix the permit to the gun case or if I carry it? A friend who has made the same trip said the gun permit has to be securely taped to the outside of the gun case. Any insight from those who have flown through Amsterdam with rifles would be appreciated. I submitted paperwork on time through a travel agent, but I have not received any paperwork regarding Amsterdam. I know I should just wait for an answer from the travel agent, but I think the real experts on all this stuff are often right here on the forum. Thanks, Randy.
