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' global Aviation practice 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. He also represents 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. Under Bob's leadership, Chambers USA has consistently ranked Hogan Lovells as the top U.S. aviation law firm.

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. He advises clients on domestic and cross-border acquisition; financing and leasing of aircraft, engines, and spare parts; Unmanned Aircraft Systems (drones); negotiating and obtaining government approvals of global antitrust immunized joint venture alliances; and complex airport privatization (P3) projects. 

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

"The team is praised for their '[a]viation industry knowledge, with appropriate business-oriented solutions."
