Jetstar Japan

Launch (2012–2014)

Initially planned to commence flights in late 2012, Jetstar Japan launched ahead of schedule on 3 July 2012 using Tokyo's Narita International Airport as a base. On 6 April 2012, the airline was granted an air operator's certificate by the Japanese Ministry of Land, Infrastructure, and Transport (MLITT), in preparation for the airline's launch of services. The first route to be served was between Tokyo Narita and Fukuoka on 3 July 2012, while services between Tokyo Narita and Okinawa (Naha Airport), Osaka (Kansai), and Sapporo (New Chitose) began on 9 July 2012. Services from Osaka Kansai to Fukuoka and Sapporo followed afterwards, on 24 August 2012.

The airline also announced that it would establish a second base at Kansai International Airport in Osaka, and started service between Osaka Kansai and Okinawa on 28 October 2012. The Kansai base was originally planned to open on 18 July 2013, but the opening was postponed due to issues in improving maintenance procedures following a warning from the MLITT. In July 2013, the airline's chief executive officer (CEO) Miyuki Suzuki (鈴木 みゆき, Suzuki Miyuki) announced that Jetstar Japan's network strategy would be focused on the domestic market from Tokyo Narita for the foreseeable future, and that the company would try to optimize its schedule for connecting traffic with international flights operated by Australian-based Jetstar Airways. Suzuki later stated in August 2013 that Jetstar Japan hoped to decide the timing of the Kansai base opening within 2014.

While waiting for approval of the Osaka Kansai base, Jetstar Japan opened a number of additional domestic routes from Tokyo Narita, and announced the establishment of a new base at Nagoya's Chubu Centrair International Airport. On 31 March 2013, Jetstar launched service from Tokyo Narita to Oita and Kagoshima, while also adding three routes from Nagoya Centrair to Fukuoka, Sapporo, and Kagoshima on the same day. On 31 May 2013, the services from both Tokyo Narita and Nagoya Centrair to Kagoshima commenced, while on 11 June 2013, Matsuyama Airport became Jetstar Japan's ninth destination with services to Tokyo Narita. On 10 December 2013, Jetstar Japan launched twice daily service between Tokyo Narita and Takamatsu Airport.

Following airport maintenance delays, Jetstar Japan's base at Osaka's Kansai International Airport opened in June 2014, with frequencies increased on the airline's existing routes between the airport and Fukuoka, Okinawa, Sapporo, and Tokyo Narita. While no new routes were added to the base at its induction, Jetstar Japan announced on 16 July 2014 the addition of daily service to Oita Airport from 9 October 2014, and announced further expansion on 20 August 2014 with the addition of twice daily service to Kumamoto Airport starting on 26 October 2014. Additionally, twice daily service to Kumamoto was also planned from both Nagoya Centrair and Tokyo Nartia on the same date.

Following the opening of the airline's Osaka Kansai base in June 2014, CEO Miyuki Suzuki confirmed that deliveries of the airline's remaining A320s on order would be slowed down and spread throughout the next fiscal year. She also stated Jetstar Japan's plans to commence international operations in the coming winter season, with initial destinations under consideration being within four or five hours of travel time from the airline's Tokyo Narita base.

In July 2014, Jetstar Japan announced the establishment of codeshare and frequent-flyer program agreements with parent airline company Japan Airlines, a fellow Oneworld airline of its own parent airline company Qantas. This gave the airline a distinction from traditional low-cost carriers, such as Peach and Vanilla Air, which were both affiliated with All Nippon Airways but lacked similar agreements with ANA. Additionally, Jetstar Japan began offering international connections with both Japan Airlines and Australian-based Jetstar Airways. From October 2014, American Airlines joined as a codeshare partner, followed by Jetstar Japan's own parent company airline Qantas which joined as a codeshare partner in January 2015.

International services and expansion (2014–2026)

On 3 December 2014, Jetstar Japan announced the long-delayed commencement of international service, with its first service to connect Osaka Kansai with Hong Kong International Airport. The service was planned to initially operate three times per week, with additional frequencies added over time. On 16 March 2015, it was announced that services to Hong Kong would increase with two additional weekly frequencies, operating five weekly flights from 18 July 2015 to 31 August 2015, and four weekly flights from 1 September 2015 to 24 October 2015. On 21 January 2015, Jetstar Japan announced a new daily service between Nagoya Centrair and Okinawa would commence from 29 March 2015. However, the net amount of services from Nagoya Centrair were planned to remain the same, with the service to Okinawa replacing one of the two daily services to Kumamoto.
