EasyJet has agreed to purchase 56 Airbus A320neo aircraft and convert a previous order to 18 new A321neo aircraft, the British airline said on Tuesday.

According to the company, deliveries of the aircraft, which have a list price of $6.5 billion, will begin in the carrier’s 2026 financial year to replace the carrier’s older A319 and A320 aircraft.

“The proposed purchase firms up EasyJet’s order book with Airbus, continuing the company’s fleet refresh, as A319s and older A320s leave the business and new A320 and A321 neo aircraft enter providing up gauging, cost and sustainability enhancements to the business,” it said in the statement.

“The directors believe this will support the delivery of our strategic objectives and provide the aircraft to help build strong shareholder returns.”
