>Where do you find this information at?
I just picked it up from the trips I've made.
(one sign in the Chicago airport, I think it was, warns people that certain items are not permitted on the flight. Along with knives and lighters, there is a picture of one of those "cartoon" bombs--you know, the ones that look like bowling balls with a fuse sticking out of them. Luckily, I didn't have one of those with me!)
You can find travel tips at places like
www.orbitz.com , and probablyy at the website of any airline. They will most likely have a list of what you can't take, and some tips to make your check-in faster.
One tip: wear shoes that have no metal in them, so you don't have to remove them to go through the metal detector. A lot of shoes have metal lasts, and you'll have to take them off. I love to travel with my "airport friendly" Earth Shoes (they came with a tag that says so!).
