Eurocontrol data shows that four of the top five busiest air routes that touched Europe last year were to or from London, underlining the UK capital's importance to the continent's air flows. Across the air traffic manager's coverage region, which stretches from Georgia in the east to Iceland in the North Atlantic, the Dublin-London route was the busiest one, with an average of 91 daily flights through 2024. The route between the Irish and UK capitals was the 27th busiest route globally. In the European ranking, it was followed by London-Amsterdam (84), Antalya-Istanbul (69), and London-New York and London-Edinburgh (both on 65). Eurocontrol notes that Amsterdam-London was the 37the busiest route globally, but its average of 84 daily flights is down from 105 in 2019, when it was the busiest European route. The air traffic manager attributes this to improved rail links between the two cities. Globally, Asia dominates the busiest city pairs, with 45 of the 100 busiest routes, led by Jeju-Seoul in South Korea with an average of 226 daily flights. This is followed by Melbourne-Sydney (157), Rio-Sao Paulo (152), Sapporo-Tokyo (147) and Fukuoka-Tokyo (137), the same top five as in 2023. New York featured in the highest number of top 100 city pairs (13), followed by Tokyo (eight) and London (seven). Separately, Eurocontrol says that across the week of 3-9 February traffic in Europe by number of flights was up 5% on last year, at nearly 25,000. Overall, year-to-date network air traffic is at 95% of 2019 levels.

Aviation Capital Group has delivered one Boeing 737 Max 8 to Italian carrier Neos. This marks ACG's first aircraft delivery to Neos, the first of three 737 Max 8 jets scheduled to be delivered to the carrier from ACG's Boeing orderbook, the US lessor says. "These advanced, fuel-efficient aircraft will enable Neos to further strengthen its position as one of Europe's premier charter airlines, enhancing their operational capabilities while supporting their commitment to sustainability and fleet modernisation," states ACG's executive vice-president Carter White.

Safran expects to gain certification this year for new high-pressure turbine parts designed to increase CFM International Leap-1B engines' time on wing. The US Federal Aviation Administration and European Union Aviation Safety Agency in December 2024 approved a similar durability kit for Leap-1A engines. Leap-1B engines power Boeing 737 Max narrowbodies, while the Leap-1A is an option on Airbus A320neo-family jets. Olivier Andries – chief executive of Safran, a joint parent of CFM alongside GE Aerospace – said during an earnings call on 14 February that the two manufacturers had recently begun using the improved hardware for engine production and in overhaul shops, and that it was therefore too early to assess the equipment's in-service performance. However, citing pre-certification endurance tests, he adds: "We are very confident that the time on wing will double." CFM said in December the new hardware would "ensure that Leap-1A engines achieve the same level of maturity, durability, and time on wing that our customers have enjoyed with the CFM56 product line". The Leap-1A durability kit includes an HPT stage 1 blade and nozzle, and forward inner nozzle support structure. Andries notes that the improvements will be especially relevant for operators in hot and dusty environments. He foresees that the durability kit will serve as a "trigger" for CFM hour-based Leap-1A support agreements to become profitable in 2025. GE in January said that aftermarket services for Leap engines had become profitable last year, and that the entire programme was on track to break even in 2025. The US manufacturer expects that original equipment production will break even in 2026.
