There is an incredible story out of England about an 11 year old that ran away from his mom at the mall. He decided to head to the local airport and somehow was able to get past security without a passport or a ticket.
He was then able to board the flight and it was only half way to Rome before the passengers and flight crew became suspicious.
Once they landed in Rome, they contacted his mom and he was put on the next flight back to England.
It begs the question – did they let the 11 year old earn miles for the flights? 🙂
