Trenton-Mercer Airport (TTN/KTTN) is a county-owned public airport in Ewing Township, New Jersey, about four miles northwest of downtown Trenton. It opened in 1929 and today mixes general aviation with limited commercial service, primarily by Frontier Airlines to leisure destinations. Its compact terminal and location between Philadelphia and New York make it a convenient alternative to larger regional airports.
💡 Local Tip
Frequent visitors know the terminal is small enough to park and reach security in minutes, but Frontier’s early-morning Florida departures can create a sudden bag-drop and security crunch. Arrive at least 90 minutes before departure and use the closer long-term lot for the shortest walk.
🚖 Getting There
By car, TTN is easily reached from I-295 and Route 1, with signed exits leading to Terminal Circle Drive; from Philadelphia take I-95 north to I-295, and from New York take the NJ Turnpike to I-295. NJ Transit bus service, including Route 608, provides a public transit link to Trenton Transit Center, though service can be infrequent, so check schedules. Taxis, rideshares, and on-site rental cars are available, and parking is close to the terminal.
