Nope, sure don't. Small gold chain, stud or small hoop earrings.

Less to lose, also flying can cause swelling that would make rings uncomfortable. Big earrings get in the way of my NC headphones.

I suppose it depends on how you travel. If you're going to a wedding or plan to do a lot of upscale eating out or impressing clients then I might take a small selection, otherwise I think it just attracts unwanted attention and is one more thing to worry about losing.
