The opening was postponed due to a control tower attack just before the opening. This commemorative ticket had the opening date of the new line printed on it, so it was never used. However, due to the requests of enthusiasts nationwide who knew about this situation, the "Phantom Commemorative Ticket" was released to coincide with the 5th anniversary of the airport line's opening. It is a phantom commemorative ticket.
