nene205~don't stress too much about
it! I have flown many times both in the US and International with ease!!
Just like Smd729, the only time I had to even pause going through the scanner was when I didn't empty right before getting into line for TSA. And, even then, I didn't have to do anything more than a quick pat down on my back pocket (yes, that's where it showed up, LOL).
Enjoy Germany
