PT Lion Mentari Airlines

Lion Air, operating under the legal name PT Lion Mentari Airlines, is an Indonesian airline that provides scheduled passenger transportation services. The company focuses on offering low‑cost air travel, maintaining a fleet that serves both domestic routes within Indonesia and selected international destinations across Asia and the Middle East. Its core business revolves around moving passengers efficiently while emphasizing affordability and frequent flight schedules.

Although specific quantitative metrics such as fleet size or annual passenger numbers are not supplied in the source material, Lion Air is recognized as one of the largest carriers in Southeast Asia, with a notable presence in the Indonesian aviation market. The airline’s operational footprint includes multiple hubs and a route network that connects major cities throughout the archipelago as well as overseas gateways, contributing to regional connectivity and tourism.

Distinguishing attributes of Lion Air include its positioning as a low‑cost carrier that has pursued rapid expansion since its inception, and its involvement in a significant cybersecurity incident. In April 2018, the company was identified among several international organizations compromised by the Winnti malware, a threat linked to a Chinese state‑aligned hacking group that used phishing emails targeting HR departments to gain persistent access and exfiltrate data. This event highlighted the airline’s exposure to sophisticated cyber threats despite its primary focus on aviation operations.

While the source material does not explicitly detail Lion Air’s ownership structure or parent‑subsidiary relationships, the available information confirms its headquarters are located in Indonesia and that it operates under the aliases Lion Air and PT Lion Mentari Airlines. The airline continues to function as a key player in the Indonesian air transport sector, balancing its commercial objectives with the need to address emerging cybersecurity risks.
