Morristown Municipal Airport — Morristown, United States

Morristown Municipal Airport (MMU) is a busy general aviation reliever airport located in Morristown, New Jersey, serving the northern New Jersey business and corporate aviation market within commuting distance of New York City. MMU is one of the East Coast's most active general aviation airports, handling significant volumes of corporate jets, charter flights, and private aircraft rather than scheduled commercial airline service. Its proximity to Manhattan makes it a preferred alternative to congested major airports like Newark or Teterboro for business travelers and high-net-worth individuals. The airport features full-service fixed-base operators, extensive hangar facilities, and has long played a role in the region's aviation and business infrastructure, reflecting the affluent Morris County area it serves.
