Southwest Airlines and Singapore Airlines (SIA) have launched an interline partnership that further extends the US carrier's international reach. In December 2025, Southwest and Turkish Airlines agreed an interline deal connecting the Dallas-based carrier's customers with more than 350 destinations from the European carrier's Istanbul hub. Singapore Airlines and sister carrier Scoot fly to more than 130 destinations, among them three US airports served by Southwest: Los Angeles International, Seattle-Tacoma and San Francisco International. "Journeys that pair Southwest and Singapore Airlines not only connect new geographies but also create consistent high-quality customer experiences," states Southwest chief operating officer Andrew Watterson. Southwest notes that, with the addition of SIA, it now has eight airline partnerships spanning destinations in Asia, Europe, the Middle East, and Africa. The carrier's chief executive Bob Jordan said on 28 May during the Bernstein Strategic Decisions Conference that Southwest intends to offer customers "access to destinations" that it does not serve, adding that "it's likely" that it will eventually "delve into long-haul international".

Airbus has been engaged to provide Lufthansa Group carriers with A220 component support. The aftermarket services agreement was disclosed by the airline group as it commemorated the 50th anniversary of its first delivery from Airbus, at the ILA air show in Berlin. Cirium data shows that Lufthansa subsidiary Swiss has 30 A220s (21 -300s and nine -100s), while ITA Airways, another group carrier, has 31 (19 -300s and 12 -100s) and one more on order (a -300). Lufthansa is scheduled to receive this year the first of 40 A220-300s on order for its City Airlines subsidiary. As part of its 2023 order of A220-300s for City Airlines, Lufthansa took 20 options. The new support deal is noteworthy as Lufthansa previously sourced component maintenance in-house or, in the case of its A380s and Embraer E-Jets, from the Spairliners subsidiary jointly owned by Lufthansa Technik and Air France Industries. Since taking delivery of its first Airbus jet in 1976, Lufthansa has operated A300/A310s, A320-family jets, A330/A340s, A350s, A380s and A220s. Later this year, it notes, it will receive its 700th aircraft from the airframer. Lufthansa Group chief Carsten Spohr describes the collaboration with Airbus as a "long-standing, trusting, and very special partnership". "Over the past half-century, we have not only taken delivery of more aircraft from Toulouse and Hamburg than any other airline in the world, but have also supported the development of numerous aircraft models as launch customers," he states, adding: "We intend to build on this foundation together to further advance aircraft technology and expand Europe's leading role in the aviation sector."

Africa World Airlines will deploy its first Embraer E190-E1s next month as part of efforts to increase its fleet capacity. Speaking on stage at the AviaDev conference in Gaborone on 10 June, Sohail Mahmood, the carrier's operating chief, says two of the regional jets will enter AWA's fleet in July to complement its existing fleet of ERJ-145s. He says adding a larger aircraft type has been discussed for several years, but there was now a risk that Ghana, and West Africa more generally, are on a "precipice" where "growth is missed", requiring the African carrier to increase its fleet operational range and capacity. Speaking to Cirium, Mahmood says that AWA will purchase the jets outright from its shareholder Hainan Airlines rather leasing them or leveraging its balance sheet. He adds that the airline plans to purchase up to 10 E190s and is considering possible sellers. Cirium data shows that it has six ERJ-145s in service and one that is in storage. All are managed by Hainan Airlines' parent company HNA Group.
