In practise, the Schengen agreement does not entirely protect you from the security checkpoints in the airports. It just frees you from the passport control. I used to love to fly but now actively avoid it. I've been groped, accused, shoved, stolen from, stripped down and set to wait enough that I simply don't enjoy it anymore. All that said, I still find the US TSA even more ridiculous and slow.
