春秋航空
In July 2011, ANA and AirAsia announced that they would form a low-cost carrier subsidiary, AirAsia Japan, based at Narita. Later in 2011, JAL and Jetstar Asia announced a similar low-cost joint venture, Jetstar Japan, to be based at Narita. Skymark Airlines opened a domestic base at Narita in November 2011, and by February 2012 was operating 70 departures per week from NRT. Skymark cited the lower fees at NRT as a key reason for this move. Spring Airlines Japan, an LCC partly owned by Spring Airlines, plans to begin service in 2014 with NRT as its primary base.
