When I was went travelling, we decided in Seattle that we didnt have enough cash to stay for the 3 weeks when our flight home was so we enquired about getting a one way ticket from Seattle to London and was told it would be cheaper to get a return but under US laws, it would be illegal not to make the return trip! Now that's wierd too.
Anyway, we got a return and went back to Seattle for a long weekend flying home on our original tickets
