KMMU is the ICAO code for Morristown Municipal Airport (IATA MMU), located in Morristown, NJ.
Morristown Municipal Airport (KMMU) sits in Morris County, New Jersey, 28 miles west of midtown Manhattan and 35 miles north of Newark. It is one of the principal Teterboro alternatives for NYC-area business aviation, particularly favored by corporate flight departments based in northern New Jersey and the Morristown corporate corridor. There is no scheduled commercial service; the field is purely business and general aviation.
Runway 5/23 is 5,999 feet and runway 13/31 is 4,003 feet. Heavy and ultra-long-range jets operate routinely from KMMU, though planners with maximum payloads sometimes use KTEB or KEWR for longer departures. Signature and Jet Aviation are the two FBOs, both with substantial hangar capacity for based fractional fleets. KMMU's appeal for brokers is straightforward: no slot pressure (unlike KTEB or KHPN), full FBO services, easy 5–10 minute drive into the New Jersey corporate cluster, and 45–75 minute drive into Manhattan depending on traffic. Field elevation is 187 feet, no density-altitude concerns. The dominant operational issue is winter weather — snow, freezing rain, and occasional ramp closures match the northeast pattern. Bridge and tunnel traffic into NYC is the real variable; brokers routinely add buffer for Friday-afternoon eastbound trips.
Morristown Airport is in Morris County, New Jersey, United States, three miles east of downtown Morristown and 40 miles west of Manhattan, New York City. Operated by DM AIRPORTS, LTD, it is in the Whippany section of Hanover. The National Plan of Integrated Airport Systems for 2011–2015 called it a general aviation reliever airport.
