Every time I tried to book a domestic flight in another country, the prices were always exorbitant. But, say, once I was in Bangkok, that same flight that was once $300 would fall to $30 almost inexplicably. This phenomenon is because a ticket’s point-of-sale (POS)—the place where a retail transaction is completed—can affect the price of any flight with an international component. Most people don’t know there is a simple trick for “changing” this to get a cheaper flight on an airline’s website; it’s how I managed to pay $371 for a flight from New York to Colombia instead of $500+. Though it can be used for normal international flights, it often works best when you’re buying domestic flights in another country.

For those of you who commented that you were worried about hidden city ticketing during that post, this is very different. You are simply changing your sales city.
