Henna Haroon & Associates adds former airline executives to aviation practice

Henna Haroon & Associates said July 13, 2026, that Patrick Fennell and Choorah Singh have joined the firm as Associates in Dublin, expanding its aviation practice with senior operational expertise. The additions are meant to strengthen the firm’s ability to pair commercial strategy with hands-on airline execution across Europe, Asia and the Middle East.

Why it matters: - Henna Haroon & Associates is pushing its aviation practice beyond strategy work and into airline operations. - The move pairs commercial advisory with executives who have led airline transformations, fleet integrations and live operational turnarounds. - The firm is aiming to help clients close the gap between boardroom plans and day-to-day execution.

What happened: - Henna Haroon & Associates announced from its European hub in Dublin that former airline executives Patrick Fennell and Choorah Singh have joined as Associates. - The firm said the hire advances HH&A beyond its commercial roots and cements aviation as its flagship practice. - HH&A said the additions build on its existing aviation bench that includes Tony Merrigan, Principal Associate & Senior Advisor, a former Irish Aviation Authority executive. - HH&A continues to serve clients across aviation, energy, technology and private equity.

The details: - Fennell has more than 20 years of leadership experience and more than a decade in C-suite roles across airline operations, strategy and transformation. - His experience spans Europe, Asia and the Middle East. - Fennell has held leadership roles at one of Asia’s largest airlines, regional carriers in Europe and specialist operators in the Middle East. - His background includes operational and digital transformation, regulatory affairs, airline start-ups, restructuring, MRO strategy and executive advisory. - Singh has more than two decades of airline operations experience across Europe and Asia. - Singh has led operational and digital transformations at Ryanair and Air India. - Singh has guided complex fleet integrations and built operational frameworks for high-growth airline startups. - Singh specializes in operational performance, systems modernization and the integration of applied AI into live airline environments. - Singh is completing a Diploma in Advanced Artificial Intelligence in Business at University College Dublin. - HH&A said its model rests on judgment, access, credibility and embedded execution. - The firm said it deploys senior practitioners who work inside a client’s business, adapt to real-time challenges and stay until the job is done. - HH&A said it helps global companies in aviation, energy and technology with positioning, commercial strategy and demand generation. - HH&A said it also works across market positioning, infrastructure development and strategic operations. - The company is headquartered in Houston and has a deep footprint in Europe.

Between the lines: - The hire signals that HH&A wants to compete on execution, not just advisory language. - Aviation clients are under pressure to make technology and restructuring initiatives work in real operating conditions, not just in planning decks. - Fennell and Singh bring experience from different parts of the airline value chain, which could help HH&A sell broader transformation projects. - Their appointments also reinforce Dublin as a base for the firm’s European aviation push.

What's next: - HH&A is likely to market aviation engagements around operational transformation, digital modernization and AI-enabled workflow change. - The firm may lean more heavily on its new associates for client work in Europe, Asia and the Middle East. - HH&A will continue building around aviation as a flagship practice while keeping its energy and technology advisory work in place.

The bottom line: - HH&A is turning aviation into a deeper operating practice by adding airline veterans who can help clients execute, not just plan.
