“This is Jetstar’s 20th year of flying, and these new aircraft and our 787 cabin revamp program will allow us to grow our domestic and international network, unlock new destinations, provide more great low fares, and further strengthen our reliability,” said Jetstar’s chief operating officer, Matt Franzi.

Jetstar is expecting another five A321neos by the end of the 2024 calendar year, as part of a total order of 38 A321neo LR and XLR aircraft by 2029. The airline has also ordered an initial 10 A320neos to replace its existing A320ceo fleet, the first five of which are scheduled to arrive within the 2025 financial year.

The first NEO was delivered to Jetstar at the end of July 2022. The airline says the NEO’s more fuel-efficient LEAP engines burn up to 20 per cent less fuel than Jetstar’s previous A321 planes and are up to 50 per cent quieter.

According to Jetstar, the NEO fleet reduced emissions by more than 16,000 tonnes in its first year of flying, and has freed up its 787 Dreamliner fleet for longer international routes.

Additionally, Jetstar says the NEOs have boosted its operational performance with their 99.8 per cent mechanical reliability.

Jetstar CEO Steph Tully last year hailed the aircraft as a “game-changer” for the airline.

“These longer range, highly fuel-efficient aircraft help us achieve our Qantas Group emissions reduction targets while also delivering great low fares to more destinations,” she said.

“Our customers love them. They are 50 per cent quieter, have huge overhead bins and wider seats, and customers can stream entertainment on their own devices.”

Jetstar is also refreshing its 787-8 Dreamliner fleet starting in FY25, which the airline says will enable longer-haul travel including to destinations such as India, Sri Lanka and Africa.
