At your age, you can probably take a month or two and have a great experience in Europe. (It's easiest to do the travel vagabond experience in Europe when you are a college student, trust me ). For your 2K miles on AA, you could certainly do an AA or OneWorld J award to someplace in Europe and then use your BA miles to fly to different cities within Europe. Don't forget trains either. Although your AA miles won't work on the trains , a train is the best way to travel from Prague to Budapest IMHO, and you could certainly adequately visit both those cities even if you only have a weeklong vacation.
