Airport security

Be careful what you put in your case, going self catering leave those coco pops for the kids at home anything foil packed will get your case opened before you fly.

Put mobile phone - camcorder and other chargers and batteries together where they can easily be seen and identified.

Place your name - flight number and mobile phone number inside each case,  if opened  you can easily be found and your case put back onto the flight without to much delay, don't put silly things in your carry on baggage which can cause your flight to be delayed or the pilot refusing to let you board.
