Alton Aviation Consultancy registers another year of record growth in 2025
New York – February 10, 2026: Alton Aviation Consultancy, a leading global aviation advisory firm, reports another solid year of growth in 2025 as demand for premium aviation advisory services remains strong.
Continued growth in Alton’s advisory work increased across virtually all segments of the aviation value chain to include aircraft leasing and financing advisory, airline due diligence, restructuring, and fleet campaigns, and maintenance, repair, and overhaul (MRO) advisory, in addition to supporting airports and business and general aviation (BGA) sectors. Across all sectors, merger and acquisition (M&A) transaction advisory activity remained robust.
In 2025, the firm successfully completed more than 200 engagements for over 100 organizations, with approximately two-thirds coming from repeat clients. This further underscores the value delivered through Alton’s deep domain expertise, and the firm’s high degree of client responsiveness and commitment to excellence.
Alton extended its global footprint with the addition of its London office, strengthening its ability to support clients in the UK and Europe with regional insight across major aviation markets. The new entity builds on Alton’s established global platform which includes New York, Dublin, Dubai, Hong Kong, Beijing, Singapore, and Tokyo. The firm also had a strong year for talent development, with 16 employee promotions across its global team.
In addition, Alton continued to support global and local communities through its commitment to the Pledge 1% movement for corporate impact, electing to donate 1% of annual revenue to charity and dedicating 1% of employee time to volunteer work. In 2025, Alton’s lifetime charitable contributions exceeded the $1 million mark.
John Mowry, Managing Director, Alton Aviation Consultancy, says: “Our strong performance in 2025 was underpinned by the experience of our team and demonstrates the value of combining deep aviation expertise with practical, execution-focused advice. As market dynamics shift, investing in our people remains central to how we deliver consistent, high-quality outcomes for clients.”
Adam Cowburn, Managing Director, Alton Aviation Consultancy, adds: “In 2026, we expect continued opportunities for M&A transactions, supported by improving market fundamentals, although supply chain challenges and broader macroeconomic factors will remain important considerations for industry stakeholders. Alton is well positioned to support clients as they evaluate complex opportunities and navigate an evolving market.”
