Why is jet star so cheap?

Jetstar offers lower fares primarily by adopting a no-frills business model, which reduces operational costs. They charge extra for add-ons like checked baggage, seat selection, and in-flight meals, allowing passengers to pay only for what they need. Additionally, Jetstar often operates in competitive markets, which drives prices down. Their use of a single aircraft type and point-to-point routes also contributes to cost efficiency.
