Global investment firm KKR has announced a new $1.4 billion equity commitment to expand its commercial aircraft leasing portfolio in partnership with aviation leasing and financing specialist Altavair, further strengthening a long-standing collaboration with a growing emphasis on cargo aircraft and passenger-to-freighter (P2F) conversion opportunities.
The latest investment builds on two previous aircraft leasing portfolios established by KKR and Altavair and follows KKR’s continued strategic expansion in the aviation sector, including its increased ownership stake in Altavair and its affiliated company AV AirFinance announced earlier in 2026.
Funded from KKR’s balance sheet and supported primarily through its Infrastructure and Asset-Based Finance strategies, the new capital commitment reflects increasing opportunities in acquiring, financing and leasing both passenger aircraft and dedicated freighters as global air cargo networks continue to evolve.
Growing Focus on Freighter Assets and P2F Conversions
A key component of the KKR–Altavair strategy is the expansion of freighter assets, particularly through passenger-to-freighter conversion programmes. Altavair has established itself as a major participant in the P2F market, with extensive expertise in acquiring, converting and leasing Airbus freighter aircraft.
Since its establishment in 2003, Altavair has completed 33 passenger-to-freighter conversions, including one combi aircraft, and was the launch customer for two major P2F conversion programmes. The company has focused particularly on the Airbus A330P2F platform, including the range-efficient A330-200P2F and the high-capacity A330-300P2F variants.
One of the partnership’s most notable cargo transactions was the 2022 agreement under which Amazon Air leased 10 Airbus A330-300P2F aircraft owned by KKR-managed funds, with Altavair serving as lease manager. The first aircraft entered service with Hawaiian Airlines in 2023, while the remaining aircraft were introduced during 2024.
In a significant secondary-market transaction, the fleet of 10 A330 freighters was acquired by IAT Leasing in March 2026 from Altavair and KKR-managed funds, highlighting continued investor confidence in modern widebody cargo aircraft.
Long-Term Aviation Growth Strategy
Altavair works closely with aerospace and conversion specialists, including ST Engineering, Airbus and Elbe Flugzeugwerke (EFW), to deliver efficient P2F solutions that extend aircraft service life, create additional cargo capacity and generate long-term value for investors and airline operators.
The broader KKR–Altavair partnership now spans approximately 90 commercial and freighter aircraft across a diverse range of transactions, including aircraft acquisitions, lessor portfolio trades, sale-and-leaseback agreements, structured financing arrangements and cargo conversion projects.
With the latest $1.4 billion commitment, KKR and Altavair are positioning themselves to capture growing demand for flexible aircraft financing solutions and modern freighter capacity, as airlines, cargo operators and logistics providers continue adapting to changing global trade flows and supply chain requirements.
Since its founding in 2003, Altavair has completed more than $14.5 billion in commercial aircraft leasing transactions, working with over 80 airline customers across 50 countries and managing transactions involving more than 300 Boeing and Airbus aircraft.
