Just how much do state 'legal ages' limit us?

Question

Hello everyone. First of all, I am seventeen. I was always so sure that the legal age for my state was 18, when it is in fact 19. It's strange because we're allowed to marry at 18 without parental consent, but cannot get an apartment until 19 on our own will. And also, the reason I'm mainly asking this, is because I'm graduating next year and my friends and I have planned a graduation trip to Europe, and maybe some other countries. Would I have to get parental consent to go abroad, or would I just have to find an airline that considers 18 an adult? (Because I ran into one that wouldn't let you fly without consent unless you were 19) And I'm just confused about this whole thing, because it seems silly to me. I just want to know what I can or cannot do. And I need an answer or else I'll be thinking about this until my eighteenth birthday. :)

Legal ages are valid exercise of the state to regulate people in contracting marriages and agreements for it has the state responsibility.
