I was sitting on a train from Lucerne to Milan talking with some folks from Costa Rica, and they told me how expensive it is to fly from Costa Rica to the US as opposed to the US to Costa Rica. I asked, 'Why not book in the other direction?'
They couldn't, they said, because the 'outbound' leg of their journey would have to be from the US.
'Well, make it that way. Let's say you travel to the US once a year for the latter half of June. Begin by booking a one-way ticket from CR to the US for June 15, 2008. When you get to the US, book a round-trip ticket, leaving the US on June 30, 2008, and returning on June 15, 2009.
Repeat every year.
Would it work?
