Just wanted to mention, this is a very nice little airport. Well technically I guess it's midsized, being bigger than it looks from the outside. It's new and modern and dare I say pleasant, it's more like a train station with lots of eating and shopping options without having to go through security. The supermarket had a nicer selection of items than I've seen here at home, perhaps airport employees do their grocery shopping there.
One thing to note, there is a train on the premises to shuttle you to another terminal and that is probably where your international flight will depart from. So do some research and allow enough time for the shuttle (it only took about a minute and seems to run every five minutes or so). If you're planning to use an airline club, be aware that Lufthansa has dozens of clubs scattered throughout the airport and you should aim for the one closest to your gate (we got that helpful advice from one of the clubs we stopped in).
