My fiance thought this one out beautifully. Of course we waited on line together but when we got to the front, he told me to go ahead of him as he said he needed to get something from his bag. This was at the Marine Air Terminal at LGA so he asked me to pick up a few magazines afterwards while he went through security. So I went ahead first, a few others followed, I went to get the magazines, and he went through security. And nobody checked his bag.
