Seeker, have traveled alone couple times out of country, not overseas.
One of these trips was 2 months after 9/11 so security was tight.
But...all the airport personel were friendly & helpful.
I saw people escorted to their gate when overwhelmed.
If you could just make it to the airport, people will help you.

If I had the money, I'd travel alone abroad in a heartbeat.
Could get you to Europe & be on my way.
