Attorney general for the US state of Hawaii, Anne Lopez, has stressed the importance of protecting the interests of the state's people in discussions with the US Department of Transportation regarding the merger of Alaska and Hawaiian Airlines. Lopez shared several "observations and concerns", including the role affordable inter-island travel plays in the lives of Hawaiians, access to health care, advancing education, connecting families, and moving cargo, according to a 30 August DOT memorandum. She also discussed the importance of preserving inter-island flights at an affordable price and raised the concern that Alaska Airlines would repurpose Hawaiian Airlines' Airbus jets and use them to replace Boeing jets on routes that do not serve Hawaii. Lopez, who has served as attorney general of the state since 2022 and is a member of the Democratic Party, spoke with Mohsin Syed, chief of staff for DOT secretary Pete Buttigieg, as well as with Brian Stansbury, deputy general counsel for the DOT. According to a 28 August DOT memo, United's chief legal officer Robert Rivkin "expressed concerns" to Stansbury regarding the potential impact of the merger "on the co-operation agreements between United and Hawaiian Airlines".

Vistara will end services under its own operations on 11 November as its merger with Air India progresses towards completion. Air India states on its website that from 3 September Vistara's ticket sales will "gradually transition" to the Star Alliance carrier, and by 12 November all routes will be operated on the Air India operating certificate. The operational merger comes after India's government approved the plan for Singapore Airlines to take a 25.1% stake in the post-merger Air India in recent weeks, which was the last remaining hurdle to joining the two carriers. SIA currently owns a 49% stake in Vistara with the remainder held by Tata Sons, which also acquired Air India from the Indian government in January 2022. SIA and Tata agreed to merge the two carriers in November 2022. The full-service joint venture carrier launched operations in January 2015 and over time has expanded to operate a strong domestic and growing international network. Vistara is scheduled to operate over 10,000 flights during October, which will be the last full month of its operations, compared to just under 14,000 by Air India during the same month. Data shows that Vistara operates 53 Airbus A320neos, 10 A321neos and seven Boeing 787-9s, which is set to join Air India's operating fleet of 141 aircraft.

Singapore Airlines has obtained approval from the Indian government for its proposed foreign direct investment into the enlarged Air India Group, stemming from the merger of its 49%-owned company Vistara and Air India. SIA will hold approximately 25.1% of the expanded group after the completion of the proposed merger, the carrier says in a filing to the Singapore Stock Exchange. Tata Sons will hold 73.4%. The proposed merger, subject to regulatory approvals, is expected to be completed by the end of this year. Singapore Airlines disclosed its plan to merge Vistara and Tata-owned Air India in November 2022. In June, India's National Company Law Tribunal approved the scheme of arrangement to merge Air India and Vistara.
