Tomorrow I am flying from Munich connecting in Chicago (ORD) before continuing onwards. I wanted to bring some beer with me. The beer would be the only thing to warrant a checked bag. So two scenarios I am considering:

1. If I buy beer from a store before I would checkk the bag in MUC, butI know in ORD I will have to recheck my bag. Could I take the beer out and put it in my checked bag? Or will I have too go through TSA again?

2. If I were to buy beer at the airport in MUC after security, would that be a problem in ORD after passing customs (because of a possible TSA check)?

Thanks!
