PT Lion Mentari Airlines, operating as Lion Air, is an Indonesian low-cost airline. Based in Jakarta, Lion Air is the country's largest privately run airline, the second largest low-cost airline in Southeast Asia (after AirAsia) and the largest airline of Indonesia. With Wings Air and Batik Air, Lion Group is the country's largest airline's group. The airline operates domestic as well as international routes, which connects different destinations of Indonesia to Singapore, the Philippines, Malaysia, Thailand, Australia, India, Japan and Saudi Arabia, as well as charter routes to Mainland China, Hong Kong, South Korea and Macau, with more than 630 flights per day. The airline has repeatedly broken records for largest aircraft orders, such as its $24 billion order for 234 Airbus A320 jets, as well as its $22.4 billion order for 230 competing aircraft from Boeing. The airline signed an agreement with US-based aircraft manufacturer Boeing for fifty 737 MAX 10 passenger jets worth $6.24 billion in June 2017. The airline is Boeing's second-largest customer (after US-based Southwest Airlines). It had once been criticised for poor operational management in areas such as scheduling and safety, although steps have been taken to improve its safety: on 16 June 2016, the European Union lifted the ban it had placed on Lion Air from flying into European airspace. In June 2018 it attained a positive safety rating following an ICAO audit. History The airline was established in October 1999 by Rusdi and Kusnan Kirana and started operations on 30 June 2000, when it began scheduled passenger services from Jakarta to Denpasar and Pontianak using a leased Boeing 737-200. It was the first low-cost airline in Indonesia. The fleet was quickly expanded with the wet-lease of five Yakovlev Yak-42Ds, two McDonnell Douglas MD-82s and two sub-leased Airbus A310-300s. Rapid growth enabled modernisation of the fleet with Boeing 737-300 and Boeing 737-400 aircraft. In 2003 a subsidiary airline was established, Wings Air, operating flights on lower density routes. Further subsidiaries were developed including Malindo Air in Malaysia in 2012, Thai Lion Air in Thailand in 2013 and domestically, Batik Air, a full-service subsidiary, also in 2013. The airline is planning to join the International Air Transport Association (IATA) and therefore hoping to become the second IATA Indonesian member carrier after Garuda Indonesia. Lion Air failed, in early 2011, the initial IATA assessments for membership due to safety concerns. Lion Air and Boeing pioneered the
