Trenton Mercer Airport — Ewing Township, United States

Trenton Mercer Airport, designated TTN, serves the Trenton and Mercer County area of New Jersey, offering an alternative to the busier airports of Newark and Philadelphia for regional travelers. The airport handles scheduled commercial service alongside significant general aviation and corporate flight activity, benefiting from its central location within the Northeast Corridor. TTN's relatively uncongested terminal and shorter security lines make it attractive for travelers avoiding the delays common at larger New York and Philadelphia-area hubs. The facility includes multiple runways capable of handling narrow-body jets, and it has seen periodic growth in low-cost carrier service. As New Jersey's capital-region airport, TTN plays a supporting role in the dense, multi-airport aviation network of the greater Philadelphia-New York corridor.
