Instead of buying a ticket for one destination to another, find a cheaper, connecting flight, and just get off at the connection. For example, if you lived in South Korea, and wanted to visit Taiwan, find a flight that has Taiwan as the connecting airport, such as a South Korea to Indonesia flight. Turns out, the South Korea-Taiwan-Indonesia flight will be a lot cheaper than a South Korea direct to Taiwan flight. Savings can be 30-50%. Airlines hate this with a burning passion, but there’s not much they can do about it.
