Thanks guys! I'm really considering checking my clothes now.These suggestions about protecting my items and making my bag distinct are very helpful

I guess my biggest concern was stolen bags (whether by mix up or purposely) because the fact that security usually doesn't compare your bag ticket with the item leaves it to occur.

That really bugs me. I don't want to waste time at Lost & Found but I guess, though it's not impossible, the odds of someone taking my bag of my used, average clothing would really be slim or a desperate person.

Thanks everyone!
