Top 10 busiest European routes from Narita International Airport (2015)

A third terminal for low-cost carriers opened on April 8, 2015. Located 500 m north of Terminal 2, the new terminal incorporates several cost-cutting measures, including using decals instead of lighted directional signs and using outdoor gates and airstairs instead of jet bridges, which are intended to reduce facility costs for airlines and their passengers by around 40% on international flights and 15% on domestic flights. Jetstar Japan, Vanilla Air and three other low-cost carriers use the terminal. The terminal also includes a 24-hour food court, which is the largest airport food court in Japan, and an Islamic prayer room. It was built at a cost of 15 billion yen and covers 66,000 square meters of floor space.
