Jetstar Airways is an Australian low-cost airline headquartered in Melbourne, Australia. It is a subsidiary of Qantas, created in response to the threat posed by low-cost airline Virgin Blue (now known as Virgin Australia). The airline operates an extensive domestic network as well as regional and international services from its main base at Melbourne Airport, using a mixed fleet of Airbus A320 family and Airbus A330 aircraft.
Parent company Qantas also has stakes in sister companies Jetstar Asia Airways and Valuair in Singapore, Jetstar Pacific Airlines in Vietnam and new upcoming carriers in Asia Jetstar Japan and Jetstar Hong Kong. Jetstar shares its parent's strong competition with Australia's biggest low-cost carrier Virgin Australia. Both Tiger Airways Singapore and Tiger Airways Australia are also major competitors to Jetstar in the low-cost market.
