I am going to Germany with my dad and my twin brother this summer to this academy program to improve on my German (half my family is German, the other is Persian)and perhaps go to the Sterling,Miraphone, and Besson shops for fun. The school is in Frankfurt and I will be flying to the Frankfurt International Airport from the Dallas/Forth Worth International Airport so the security is very strict both ways. How would I take my euphonium through security so they do not abuse it and how do i take it onto the plane as well? My brother doesnt have this problem because he plays flute and everybody knows what a flute is. I will be gone for the whole month of July so not practicing is not an option. Any advice?
