Tips for Studying Abroad?

I'll be heading off to Spain in...12 days now (ah!), and I have never left the US prior to now. Any advice on what/how to pack, what to do on long flights with long layovers by yourself, best ways to keep in touch with friends/fam back home, or anything else. Any thoughts are welcome!
