Air Serbia has seen passenger numbers surge to 1.7 million through the first half of the year, an increase of 87% on last year and 59% on 2019. The gave it a roughly 50% market share it is Belgrade hub, rising to 55% in June, it states. The number of flights rose to over 19,000, a 63% increase on the same period of 2019. “The effect of good business operation is a record financial result,” it states. “According to preliminary financial reports, in the first half of the year, we achieved a profit of 22.4 million euro, which is at the level of the profit for the whole of 2022.” It repaid €20 million ($22 million) to the government of Serbia for funds received during a recapitalisation process that was launched in 2021. The company is majority-owned by the government of Serbia, with a minority stake held by Etihad, and operates a fleet of 29 aircraft. The company focusses on connecting the Balkans with Europe and select long haul routes via its Belgrade hub.

Commercial airline pilots can use artificial intelligence predictions to avoid making some contrails, an American Airlines study suggests. Contrails constitute a significant non-carbon impact on the climate from aviation. Persistent contrails, in particular, can trap heat in the atmosphere. Google Research and Breakthrough Energy, which funds technology designed to reduce carbon emissions, led the study for American. They aimed to determine if it is possible to identify atmospheric zones that are likely to create contrails, and if pilots can avoid making contrails in flight when supplied with such data. Satellite imagery, weather data and flight-path data were fed into artificial intelligence programmes to develop contrail forecast maps. Additionally, several American pilots flew 70 flights over the course of six months while using the AI-based predictions to make modifications to routes that were projected to create contrails. Based on these tests, Google Research found that flights where pilots used the AI predictions to avoid creating a contrail reduced contrail formation by 54%, as measured by distance, compared to flights where pilots did not use the AI predictions. "This first proof point – albeit on a small number of flights – shows that a commercial flight can verifiably avoid creating a contrail," American says. "Additional research is necessary to determine if this success can be replicated and scaled." In October 2022, Delta Air Lines and the Massachusetts Institute of Technology's department of aeronautics and astronautics commenced jointly testing ways to prevent persistent contrails.

Boeing in July booked orders for 52 aircraft, led by 39 orders placed by Saudi Arabian flag carrier Saudia, and delivered 43 aircraft that month. Saudia ordered 21 Boeing 787-10 aircraft and 18 787-9s to grow its widebody fleet. Luxembourgish flag carrier Luxair also ordered four 737 Max aircraft. Orders from unidentified customers included eight Max jets and one 777 freighter. This order tally for Boeing declined year on year compared with 130 aircraft orders in July 2022, and compared with 304 orders finalised in June 2023 amid the Paris Air Show. Supply chain and manufacturing challenges impacted the rate of deliveries, which declined compared with the 60 aircraft Boeing shipped in June. The largest deliveries by the US airframer in July included nine 737 Max aircraft sent to United Airlines, seven Max jets to Southwest Airlines, and four Max to Ryanair. Net orders for Boeing during 2023 as of July jumped to 467 aircraft after the airframer factored in cancellations, conversions and the uncertainty of fulfilment. The Virginia-based airframer in 2023 has so far shipped 309 aircraft as it aims to reduce its backlog while increasing its monthly jet production rate. Boeing aims to increase the Max build rate to 42 per month when there is more stability in the market, with a goal of producing 50 Max jets per month by 2026. The airframer also aims to increase the monthly production rate for 787s from its current rate of four to five per month by the end of 2023 and to a monthly rate of 10 787s by 2026.
