Airport Overview
Morristown Municipal Airport (KMMU/MMU) is one of the busiest corporate-aviation airports in the New York metropolitan area. Sited about 3 miles east of downtown Morristown and 40 miles west of Manhattan, it is operated under long-term agreement by DM AIRPORTS, LTD. A major expansion lengthened the main runway to nearly 6,000 feet and added a modern control tower and ILS, transforming MMU into a true business-jet gateway for northern New Jersey and the broader tri-state region.
Runway Capability
The airport's primary Runway 5/23 spans 5,997 feet of grooved asphalt, with the crosswind 13/31 at 3,997 feet. Runway 23 is served by an ILS plus RNAV (GPS/RNP) approaches, and the tower operates from 0645 to 2230 local. At 187 feet MSL, density altitude is rarely a limiting factor. The field handles light through super-midsize jets routinely; larger-cabin aircraft are accommodated with appropriate performance planning.
FBO & Ground Services
Two competing full-service FBOs operate at MMU — Signature Aviation and Atlantic Aviation. Both provide Jet-A fueling, hangar and ramp parking, line service, concierge, and ground-transportation coordination. Having two FBOs gives flight departments options on pricing and availability, valuable at a field with this volume of corporate traffic.
Charter Considerations
MMU is a frequent base and destination for charter into the New York metro, with strong jet positioning from its sizable based fleet — including Falcon 7X, Falcon 2000, and Citation aircraft registered locally. Because the field is well-served by based aircraft, repositioning costs are often lower than at thinner GA airports.

Customs & International Operations
Morristown offers on-site U.S. Customs and Border Protection, available weekdays 0800–1600, with after-hours and weekend clearance by appointment. This makes MMU a practical port of entry for international business-jet arrivals into the New York area without routing through Newark or Teterboro.
Noise & Operational Factors
MMU operates a voluntary noise-abatement program with a recommended overnight curfew on closed-traffic operations (roughly 2200–0830 local) and restricted hours for engine run-ups. Operators are asked to comply whenever practical. Note that as a busy reliever in the New York Class B and TRACON environment, MMU is subject to flow management and complex airspace coordination during peak periods.
Regional Context
MMU is one of several relievers serving the New York metro, alongside Teterboro and nearby Essex County (KCDW, ~8 NM). For travelers headed to western and central New Jersey or the Morris County corporate corridor, Morristown often beats Teterboro on ground time. Newark Liberty (KEWR) lies about 13 NM southeast for those needing a commercial hub.
