Robert E. Cohn

With a decades-long aviation-focused legal career, Bob Cohn is widely recognized as one of the deans of the U.S. aviation bar. He heads Hogan Lovells' Aviation Practice Group and brings a wealth of aviation industry knowledge and skillsets to client problem solving and advocacy.

Bob advises a broad array of clients spanning every sector of air transport, including major U.S. and foreign passenger and cargo airlines, regional airlines, new entrant/low cost carriers, and helicopter operators, as well as municipalities, airport owners and operators, airport developers, private equity and venture capital firms, maintenance/repair/overhaul companies, trade associations, and aviation technology companies.

Bob has been at the forefront of U.S. lawyers handling leading-edge aviation matters, including serving as general counsel to one of the first post-deregulation airlines, providing advice to clients on Unmanned Aircraft Systems (drones), advising clients on negotiating and obtaining government approvals of global antitrust immunized joint venture alliances, and advising clients on complex airport privatization projects.

Bob's practice spans every facet of aviation law, including airline licensing and compliance, airport certification and compliance, airport privatization, antitrust, airline investment structures, airport use and lease agreements, aircraft acquisitions and financing, mergers and acquisitions, U.S. Export Import Bank financings, and public private partnerships.

With his knowledge of the aviation industry and respected relationships with government agency regulators, Bob is able to "think outside the box" and bring vast insight to achieving client goals timely and efficiently.

"[A]t the very top of the game for the DOT regulatory practice."
