Ryanair will close its seven‑aircraft base at Berlin Brandenburg airport on 24 October and cut the number of flights it operates to and from the German capital by 50% over the winter. The airline cites the airport's decision to raise fees for the period 2027-29, on top of earlier post-pandemic increases. Traffic at Berlin has meanwhile fallen, Ryanair observes. All seven aircraft Ryanair currently has based in Berlin will be redeployed to European countries that have abolished aviation taxes, including Sweden, Slovakia, Albania and Italy, adds Ryanair. It will continue serving Berlin using aircraft based elsewhere, but expects passenger numbers will halve from 4.5 million to 2.2 million in 2027. "German aviation is broken," argues chief executive Eddie Wilson, adding: "It is uncompetitive, yet there is no strategy to cut aviation taxes or high airport fees – despite Ryanair warning that Germany would lose traffic, connectivity, jobs and trade." Ryanair has since 2019 closed bases in Frankfurt, Dusseldorf and Stuttgart, and ended flights to several other German airports, while continuing to expand in lower‑cost European markets. Separately, the airline has announced that from 10 November check-in and bag drops for its flights will close 1h before departure, against 40min currently. This, it foresees, will "provide more time for passengers to get through airport security and passport queues, which will reduce the very small number of passengers who currently miss their flight departure as they are getting stuck in these airport queues".

Hawaiian Airlines has become a Oneworld member, joining sister carrier Alaska Airlines in the alliance, which also includes American Airlines. The addition of Hawaiian to Oneworld coincides with media reports – including by Bloomberg on 22 April – that the carrier's parent Alaska Air Group and American have been discussing a potential revenue-sharing arrangement. American and Alaska are codeshare partners through their membership in Oneworld. The two carriers had a codeshare partnership prior to Alaska becoming a full member of Oneworld in March 2021. In September 2024, Alaska Air Group completed its acquisition of Hawaiian. Under the terms of the deal, Alaska would acquire Hawaiian while retaining the latter's brand. In response to a question from Cirium about a revenue-sharing deal with American, Alaska cited its "long-standing policy to not comment on rumours or market speculation". During an earnings call on 23 April, American chief executive Robert Isom noted that the US major has "a great relationship with Alaska". He adds: "We really look forward to building on a history that's dated back a long time, not just to Oneworld, when we sponsored Alaska into [the alliance], but [also the development of] the WCIA [West Coast International Alliance]." The alliance, disclosed in February 2020, expanded the two carriers' domestic codeshare to include international routes from Los Angeles and Seattle.

Spirit Airlines pilots have expressed support for a federal loan to be provided to the US carrier, which in August 2025 filed for Chapter 11 for the second time in 10 months. The Air Line Pilots Association (ALPA) says Spirit pilots – which the union represents – have "voiced their strong support for the Trump administration's proposed relief effort for Spirit Airlines". US president Donald Trump on 21 April observed during an interview on the CNBC TV show Squawk Box that "Spirit's in trouble". He adds: "I'd love somebody to buy Spirit. It's 14,000 jobs. And maybe the federal government should help that one out – I told my people." Cirium has asked Spirit to comment on media reports indicating that the US government may loan it up to $500 million. Ryan Muller, Spirit Airlines master executive council chair for ALPA, states that "federal relief is not a handout". He adds: "It is a loan that will allow the airline to finish the work that is already well underway, and it is the right call for 14,000 workers, nearly 2,000 pilots, the families who depend on those paychecks, and the millions of passengers who rely on affordable air travel. Any government relief must protect Spirit employees to ensure we can competitively move forward." Muller notes that "the global fuel shock now threatening this industry is not something any airline employee caused, and it is not something this workforce should be asked to absorb alone". Spirit – which on 13 March filed with the US Bankruptcy Court for the Southern District of New York a restructuring support agreement and reorganisation plan – intends to emerge from Chapter 11 in the late spring or early summer. During an earnings call on 21 April, United Airlines chief executive Scott Kirby noted that "going back into the last [presidential] administration" he has said "that the Spirit business model is fundamentally flawed and it's going to fail". Kirby adds: "I feel bad for the people [at Spirit]. A lot of them will land jobs at other airlines." Two days later, during an earnings call on 23 April, Southwest Airlines chief executive Bob Jordan noted the "tough situation" at Spirit. "You've got a lot of people that are affected," Jordan says. "But it's a tough industry. Things come around. I've been here 38 years. You have wars, you have fuel spikes, you have economic issues, recessions. "And you've got to be prepared for the long term as a business, because the shocks are going to happen."
