Is it true you're supposed to keep your suitcases unlocked when flying now?
If you use a lock it has to be a TSA approved lock. One they can open with a special (Read commonly available) key. Still something is better then nothing as it will slow a thief down. Plus unless they are TSA they probably don't want to get caught with a TSA key.
I believe it was Fdog on this board posted his method which was to use zip ties. They can cut these off easily enough. He also put a note inside and taped another zip tie on the note inside. They opened his bags inspected them and put the new zip tie on with a smiley face on his note paper.
