Someone could place a terrorist device in your luggage. For everyone s security, you ll be asked if you packed you own bags or if you left those bags unattended at anytime. If you left your bags unattended and then try to put them on the plane, security will certainly take the time to search your bags. Security can, in the interest of safety, even refuse to allow your bags on the plane. Security checkpoints are strict, which is what keeps us safe.
Safety is no joking matter at the airport and it is no place for bad jokes.
Any comments about bombs, terrorism, guns etc. Arrests have been made of those who make inappropriate jokes. If you think it will be funny to tell the security guards to carefully search your buddy s luggage because he might have a gun, plan on that search happening, along with questions and delays for both of you. Think again, you don t want that much spice in your life. Although, if you do have that ex-girlfriend, here s a valuable tip, don t let her anywhere near your luggage.
