I'm 18(almost 19) and I want to see my gf that's lives in the netherlands Europe, and I'm from the US. Problem is this wouldn't only be my first international flight, but my first flight ever in general(Alone). My curiosity comes from my lack of knowledge about airports and customs. I want to make sure I'm mentally and legally prepared to make this happen. So I ask am I too young? And what would be a budget that can get me there and back? I plan to stay for about a week.(ill be staying with my gf so hotel expenses are excepted). And any tips you can give about airports or customs?Thanks, //the things people do for love -_-
