Trenton Mercer Airport (KTTN/TTN)

Trenton Mercer Airport (KTTN) is a medium airport in Ewing Township, NJ. Pilots and dispatchers reference it by ICAO code KTTN or IATA code TTN. It sits in North America.

Trenton Mercer Airport is a regional commercial airport that doubles as a busy private-aviation base. Operators benefit from full instrument approaches and an FBO infrastructure scaled for regular jet traffic, often without the congestion of the nearest major hub.

The longest runway measures 6,006 ft (1,831 m), a midsize and super-midsize-class field. Representative aircraft that operate comfortably here include the Citation Longitude, Challenger 350, and Gulfstream G280. In practice this comfortable for most midsize and super-mid charter equipment.

Trenton Mercer Airport sits near sea level at 213 ft.

Local operations run on America/New_York. Scheduled airline service is light enough that it rarely interferes with charter movements, though planners should still expect to coordinate with the handling agent for international turnarounds.

SkyAccess currently tracks 2 departing and 3 arriving private-jet legs at KTTN across the next six months of operator inventory. 9 aircraft from 8 operators are based here or fly through regularly, so most empty-leg supply originates from a local fleet rather than out-of-town repositioning.

Regional fields like KTTN are a meaningful share of US private aviation — closer to the trip's actual origin or destination than the nearest major hub, with shorter ramp-to-cabin times that are the main reason owners and brokers prefer them.

Trenton–Mercer Airport is a county-owned, joint civil–military, public airport located four miles (6.4 km) northwest of Trenton in the West Trenton section of Ewing Township, Mercer County, New Jersey, United States.
