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.

Gatwick airport is limiting flight movements to 800 per day until 1 October due to a lack of air traffic controllers at the facility. The decision was taken alongside air traffic service provider NATS, who run the airport’s control tower, and is designed to prevent last-minute cancellations and delays. Gatwick attributes the lack of capacity to sickness, including Covid. "We are working closely with NATS to build resilience in the control tower, and this decision means we can prevent as much disruptions as possible," states Gatwick chief executive Stewart Wingate. NATS comments that it has trained as many air traffic controllers "as possible" this year at Gatwick, but that "with 30% of tower staff unavailable for a variety of medical reasons including covid, we cannot manage the number of flights that were originally planned for this week." It expects operational resilience at the airport to improve coming into the autumn, with a new tranche of controllers set to qualify ahead of peak season 2024. "Even an experienced air traffic controller takes at least nine months to qualify at Gatwick and very few are able to do so, as Gatwick is such a busy and complex air traffic environment," it says. The latest restrictions will result in the cancellation of 164 services in total, with 29 September seeing the largest number – 65 cancellations. It follows on from disruption at the airport earlier this month caused by a shortage of NATS air traffic controllers, which resulted in calls for widescale reform of the organisation from airlines. “This cannot be allowed to continue. Immediate action must be taken to fix the staffing shortages now while a more wide-ranging review examines broader issues to ensure NATS delivers robust services to passengers now and in the future,” says EasyJet’s chief executive Johan Lundgren. Even before this, in August, an outage at NATS saw the system for processing flights across the UK and its backup fail, resulting in significant delays and cancellations across the country, enraging airlines. That was estimated by IATA to have cost carriers up to £100 million ($124 million).
