The General Court of the European Union has dismissed an attempt by Southwind Airlines to overturn a European flight ban enacted due to its alleged Russian links. In a ruling on 6 August, president Marc van der Woude dismissed an application from Cortex Havacilik ve Turizm Ticaret, which operates flights under the name Southwind, which sought to overturn a flight ban enacted in March 2024 under EU regulation No 833/2014. The airline also sought to overturn EASA's decision to remove its aircraft from an approved list of those that are authorised to operate in the EU territories under a third-country operators authorisation. Southwind in March been refused permission by Finnish authorities for its aircraft to operate to the country. On 23 March, Finland's transport and communications agency Traficom issued a statement in which informed Southwind Airlines that it would not be permitted to operate flights to Finland. Based on Traficom's overall assessment, the substantial ownership and effective control of the airline was "not vested in the contracting party designating it or in its nationals, as would be required by the applicable air services agreement. Therefore, the operations by Southwind Airlines would not be permissible under the EU Sanctions Regulation (Council Regulation (EU) No 833/2014)." "Our overall assessment shows that the substantial ownership and effective control of Southwind Airlines is not held by the stated Turkish individuals or companies. We have concluded that the airline and its control are linked to Russian stakeholders", stated director general Jarkko Saarimaki. In his ruling, van der Woude states that EU regulation No 833/2014 does not constitute an act against which annulment under the separate article 263 TFEU may be brought and that the application for interim measures must therefore be dismissed as "inadmissible on that basis".

The US Federal Aviation Administration is seeking to strengthen and standardise cybersecurity protections for aircraft and their engines after it found some of its current regulations to be "inadequate and inappropriate" amid the growth in connected systems. "Aircraft, engines, and propellers increasingly incorporate networked bus architectures susceptible to cybersecurity threats. These threats have the potential to affect the airworthiness of the airplane," the FAA states in a 21 August notice of proposed rulemaking. With regard to engines, it says that "unmitigated cyberattacks can adversely affect the propulsion control functions needed for safe operation of the aircraft" and "such attacks could also cause data corruption in crew displays and in health monitoring parameters used in operation and maintenance decisions". Security vulnerabilities can come from several sources, including field loadable software, maintenance laptops, airport or airline gate link networks, public networks, wireless aircraft sensors and portable electronic flight bags. The proposed changes would "introduce type certification and continued airworthiness requirements to protect the equipment, systems, and networks of transport category airplanes, engines, and propellers against intentional unauthorised electronic interactions". The FAA goes on to say that the substance of the proposed rules "codifies the substantive requirements of frequently-issued cybersecurity special conditions" that have been in use since 2009, and harmonise it with the approaches of other regulators. It adds that the impact on applicants and operators "would not be significant" while it would also reduce certification costs and time. The FAA is now seeking public comment on the proposed rulemaking until 21 October.

The US Department of Justice's antitrust division has completed its review of the proposed acquisition of Hawaiian Airlines by Alaska Airlines without issuing an objection. Alaska says this marks "a significant milestone" in the merger's progress. The DOJ's review period has expired on 20 August after being extended three times by the regulator with the two carriers' consent. "During the DOJ’s review, Alaska worked closely with the Hawaii attorney general to reinforce and expand upon our commitments for the future of Hawaiian Airlines and to Hawaii consumers," Alaska says. "These include plans to maintain the Hawaiian Airlines brand and local jobs and continue providing strong service between, to, and from the islands." Alaska notes that the merger remains subject to further regulatory review, including DOJ approval of an interim exemption application. "Following that step, we will complete work to close the transaction, and proceed with integrating the two companies," it adds. In December 2023, Hawaiian parent Hawaiian Holdings and Alaska parent Alaska Air Group agreed to combine under a $1.9 billion deal set to close within 12-18 months of its signing.
