Something important to note: taking things out of your pockets is actually
really important at airports that use the body scanners. So even if you think you're okay with non-metal items, you won't be if you try to go through one of those things. They'll make you go through again even if it's something as small as a gum wrapper or receipt. And here's the
TSA list of prohibited items.
For international teams, most of the security stuff holds up (though you might not have to take off your shoes--it depends on the country) and you may have to go through an extra security checkpoint at your gate. They'll just have you open your bag(s) for them and give it a quick check. I've had to do this before when flying back to the US.
