Hello! I'm visiting Europe next week with my grandma. Our destination is Madrid, but we have a connection in Frankfurt.
The thing is, my grandma has an EU passport (Portugal) and I don't (only have my brazilian passport). Am I still allowed to go with her through the EU line or do we have to go through different lines? I'm not a minor, but we are traveling together and she's paying for the whole trip, so I'm not sure. Does anyone know if we'll have problem if we go together? Thanks.
