I've read a lot of threads about the love notes we receive when our luggage is searched. Some of you seem to never get yours searched, others, all the time. I've noticed for myself, my curling iron always seems to cause my luggage to be searched. I need to try to remember to roll the cord around it.

What tips do you have to avoid luggage being opened and pilfered by TSA? What types of items trigger a hand search?
