Jetstar Airways is an Australian low-cost carrier and a wholly owned subsidiary of Qantas Group, launched in 2004 as a response to the growing budget travel market. Operating both domestic Australian routes and international services across Asia-Pacific, Jetstar serves leisure and cost-conscious travelers with a no-frills model. The airline is the flagship carrier of the broader Jetstar Group, which includes affiliate carriers in Japan, Singapore, Vietnam, and formerly Hong Kong. Jetstar has grown to become one of the largest low-cost carriers in the Asia-Pacific region by passenger numbers. Jetstar competes primarily on price, offering bare-bones base fares with optional add-ons for luggage, meals, and seat selection. Its parent Qantas uses Jetstar to protect its own premium brand while capturing the budget travel segment.
