China Eastern Airlines has agreed to purchase 100 Comac C919s, marking the largest single order for the type. The aircraft are scheduled for delivery from 2024 to 2031, the carrier states. Five units are scheduled for delivery in 2024, while the numbers will be ramped up to 10 and 15 per year from 2025-2027 and from 2028-2030, respectively. The remaining 20 is scheduled for delivery in 2031. The carrier did not disclose the size of the deal, but noted that Comac has granted “substantive price concessions” resulting in a consideration that is “significantly lower”, says the carrier in a 28 September announcement to the Hong Kong stock exchange. The catalogue price of the 100 aircraft is approximately $9.9 billion. The carrier plans to finance the purchase with its own funds, loans from commercial banks and proceeds from the issuance of bonds and other financing instruments, adding that the purchase will be settled in both US dollars and Chinese yuan. “During the delivery period of the aircraft introduced, a large number of narrowbody passenger aircraft in the inventory of the company will be phased out from the fleet due to their age and lease expiry, etc,” states the carrier. China Eastern has two C919s in service, as part of an order of five it placed in 2021. It received its first delivery in December 2022, and the second in July this year. As of 26 September, the two units in service have had a combined 867 hours of commercial operation over 296 commercial flights, carrying more than 35,000 passengers, according to a WeChat post by Comac. The carrier has 431 aircraft in service and stored in its fleet, comprising 383 Airbus jets, 14 Boeing jets and two Comac units.

Pratt & Whitney will grow capacity of its Singapore overhaul shop Eagle Services Asia due to increased demand amid the inspection campaign for PW1100G engines. The facility, which is jointly owned with SIA Engineering, will lift its capacity by two third, the US engine manufacturer says. "We will increase staffing and provide extensive staff training so that we are well equipped to meet the increased demand," states vice-president of aftermarket operations Asia Pacific and Turkey Shangari Meleschi, adding: "We are dedicated to maintaining our customers' trust as we work through the impacts of the GTF fleet management plan." On 11 September, P&W parent RTX disclosed that around 3,000 PW1100G engines – up from 1,200 as predicted in July – will require inspection because the manufacturer has since determined that metal powder contamination affected component production of more parts than previously estimated. Eagle Services Asia has overhauled PW1100Gs since 2019. It additionally supports PW4000s, Engine Alliance GP7200s and GE Aerospace GE90s. P&W notes that its MRO network for PW1000G series engines has more than doubled in size since 2019.

American Airlines has followed through on its promise to file an appeal in the US district court in Massachusetts seeking to reverse the court's 19 May ruling that it and JetBlue Airways must terminate their "Northeast Alliance" (NEA). Judge Leo Sorokin of that court permanently enjoined the US major and JetBlue from continuing, and restrained from further implementing, the NEA codeshare, effective 30 days from the 19 May court order. American's chief executive Robert Isom said on 31 May during the Bernstein Strategic Decisions Conference in New York that "we've got a legal system that allows for an appeal, and we're going to do that". New York-based JetBlue on 29 June notified American that it was declining to join the mainline carrier's appeal of the ruling that ordered their codeshare be dissolved. American says in its notice of appeal filed on 25 September that it is appealing the final judgment and order entering permanent injunction handed down by the Massachusetts district court judge on 28 July, and "all orders underlying and incorporated in that judgment, including this court's May 19, 2023" ruling.
