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.
