When traveling from Seoul to Tokyo, there are typically alternate options for departure airport, arrival airport, or both. When arriving in Tokyo, most people land at Tokyo Narita, but that is not the only available airport that T'way Air flies to. Many people choose to land at Tokyo Haneda depending on where there are traveling to in the area. Alternatively, if you are looking for more options when departing from Seoul, consider Seoul Gimpo Intl which is the closest major airport to Incheon Intl that offers T'way Air flights.
