Right on! Don't joke about bombs or anything like that. Make sure you ask if you are all set and k!$$ @$$ because there must be an official 'no jokes allowed policy' when going through security. Don't say anything... act dumb and clumsy. Tell "them" you don't travel much and a nervous flyer (only if they give you trouble.) Fly under the radar and catch your plane with as little ceremony as possible.

Good Luck and have fun
