The guys over at Airliners.net have answered a question I’ve always (sorta) wondered about: If you fly to another country and, for whatever reason, you’re denied entry, who is responsible for the price of the airline ticket back home? Turns out the airline is, even if it’s your fault. This actually happened to a friend of my family (went to Brazil, was never told he needed a visa, was sent home from Sao Paulo after 11 hour flight), but I never knew the actual policy. Now you know. And that’s one to grow on.
