FLY Leasing
An Irish aircraft-leasing investment company that owned commercial aircraft and generated returns through aircraft leases managed by BBAM.
Last updated August 25, 2026
Overview
FLY Leasing was an Irish aircraft-leasing investment company focused on owning commercial aircraft and earning returns from leasing them to airline customers. Its portfolio was concentrated primarily in narrow-body Airbus A320-family and Boeing 737-family aircraft, reflecting the strong secondary-market liquidity and broad airline demand associated with those aircraft types. Rather than operating aircraft itself or managing the day-to-day commercial relationships with airline lessees, FLY relied on BBAM, an aircraft-leasing management company, to manage and execute leases and oversee the portfolio. This structure made FLY an investment-oriented aircraft owner rather than a conventional airline lessor with a large operating workforce. Its economic model depended on acquiring aircraft, placing them with airlines under lease contracts, collecting lease rentals, preserving residual aircraft value, and realizing returns through aircraft sales or other portfolio transactions. Because BBAM handled fleet-management activities, FLY maintained relatively few employees and concentrated on capital allocation, ownership, financing, and investment performance. The company’s relationship with BBAM was strategically important. In December 2012, Onex acquired a 50% interest in BBAM and invested $75 million in FLY. That transaction connected FLY with a major investment-management sponsor and strengthened the institutional framework supporting its aircraft-leasing portfolio. FLY’s fleet was reported at approximately 110 aircraft, consisting mostly of Airbus A320 and Boeing 737 aircraft. FLY remained a publicly traded aircraft-leasing investment company under the ticker FLY before its acquisition. In August 2021, Carlyle Aviation Partners announced the completion of its acquisition of FLY Leasing. The transaction ended FLY’s independent existence as a publicly traded aircraft-leasing company and placed its aircraft assets and related business within Carlyle’s aviation-investment platform. The available reference material does not provide a separate post-acquisition operating identity, current fleet composition, or detailed information about the subsequent integration of the portfolio. FLY Leasing’s significance lay in its asset-owner model: it participated in commercial aviation through aircraft ownership and leasing rather than through airline operations, aircraft manufacturing, or direct fleet management. Its business was therefore exposed to aircraft values, airline credit quality, lease rates, utilization, maintenance conditions, financing markets, and the broader cycles of commercial aviation.
History
FLY Leasing operated as an aircraft-leasing investment company based in Ireland. Its business centered on the ownership of commercial aircraft and the generation of investment returns through leasing those aircraft to airline customers. The company was not an airline and did not present itself as a full-service fleet-management organization. Instead, it used an asset-owner structure in which BBAM managed and executed leases and handled the operational administration associated with the portfolio. The portfolio was composed mainly of Airbus A320-family and Boeing 737-family aircraft. These narrow-body aircraft are widely used in short- and medium-haul commercial aviation and are supported by broad airline demand, established maintenance ecosystems, and active secondary markets. Concentration in these families gave FLY exposure to a standardized and comparatively liquid segment of the global aircraft-leasing market, although the company’s results would also have been affected by airline financial health, lease pricing, aircraft utilization, maintenance requirements, financing conditions, and residual values. FLY’s reliance on BBAM was a defining feature of its operating model. Rather than building a large internal organization to manage leases and aircraft operations, FLY focused on investment ownership and portfolio returns. This arrangement helped explain why the company had relatively few employees. BBAM’s role provided the management infrastructure for placing aircraft with airlines, administering leases, and supporting the portfolio, while FLY retained the investment exposure associated with owning the aircraft. A major ownership and management development occurred in December 2012, when Onex acquired a 50% interest in BBAM and invested $75 million in FLY. The transaction strengthened the institutional backing around FLY’s portfolio-management structure and gave Onex a direct financial connection to both the manager and the aircraft-leasing investment company. The reference material identifies FLY’s fleet at approximately 110 aircraft, with most of the aircraft being Airbus A320s or Boeing 737s. FLY continued as a publicly traded aircraft-leasing investment company under the ticker FLY. Its public-company identity distinguished it from the private portfolio-management and leasing businesses involved in administering its aircraft. The available reference material does not establish a complete chronology of the company’s founding, initial listing, individual aircraft acquisitions, or changes in fleet size over time, so those details are not specified here. In August 2021, Carlyle Aviation Partners announced completion of its acquisition of FLY Leasing. The transaction brought FLY’s aircraft portfolio and business into Carlyle’s aviation-investment platform. It also marked the end of FLY as an independent publicly traded company and explains the company’s current status as a defunct standalone brand. The available material does not provide a detailed account of the acquisition terms, post-closing integration, or whether the FLY name continued to be used for any distinct operating business. Historically, FLY Leasing represented an investment-led approach to commercial aircraft ownership. Its value proposition rested on acquiring and holding aircraft, placing them with airlines through leases, and relying on specialist external management rather than operating a large standalone leasing organization. The company’s history therefore reflects the interaction between aviation-asset ownership, institutional capital, specialist lease management, and consolidation in the aircraft-leasing sector.

Commercial aircraft operating leasesAircraft leasing
FLY owned commercial aircraft and placed them with airline customers under lease arrangements.

Lease administration and execution were handled by BBAM rather than by a large internal FLY operating organization.
Airbus A320-family aircraft portfolioNarrow-body aircraft assets
A major component of FLY’s fleet consisted of Airbus A320-family aircraft. These narrow-body jets served the short- and medium-haul airline market and formed part of the standardized commercial aircraft assets held for leasing and investment purposes.
Boeing 737-family aircraft portfolioNarrow-body aircraft assets
Boeing 737-family aircraft made up another major part of FLY’s portfolio. Their broad use by airlines supported the company’s focus on liquid, widely operated narrow-body aircraft for leasing and investment returns.
