I have a simple zippered pouch that I carry my pens in. It's been on at least 2 dozen individual flights including some to/from Europe. I've never had a problem with TSA in the US. And some times I've traveled with 5-6 inked up pens before.

The most important thing is to travel with them nib up because the change in pressure can force air out if they aren't full. I used to bag them in mini-sandwich bags too to be safe but found that to not be necessary.
