The tour is usually held two days each month, with spring and autumn programs featuring an open-top double-decker bus. Adult tickets start at 12,000 yen ($74). As different aircraft can be seen at different times of the year and day, repeat customers are common. Each tour accommodates roughly 40 people and typically sells out within one to two weeks. In May, a promotional video targeting inbound travellers went viral, with more than 15 visitors from Taiwan, Hong Kong and other locations signing up for tours in July and August. The tours are operated by Greenport Agency (GPA), a subsidiary of Narita International Airport Corp., the operator of the airport. GPA primarily provides insurance and foreign exchange services.
