Trenton-Mercer Airport (IATA: TTN, ICAO: KTTN, FAA LID: TTN), sometimes also referred to as Trenton Mercer Airport, is a county-owned, joint civil-military, public airport located four miles northwest of Trenton, in Ewing Township, Mercer County, New Jersey. Formerly known as Mercer County Airport, the airport has one scheduled airline plus general and corporate aviation. As reported in early 2014, about 325,000 passengers use the airport each year.
Trenton-Mercer is the fourth busiest airport in New Jersey with an average of 203 aircraft operations per day (after Newark's 1153 per day, Teterboro's 434 per day and Atlantic City's 205 per day).    
Frontier Airlines, which is the only airline currently serving the airport, recognizes the airport as Trenton/Princeton on their website with 17 non-stop destinations.
Federal Aviation Administration records say the airport had 24,634 passenger boardings (enplanements) in calendar year 2007, 974 enplanements in 2008, 561 in 2009, 853 in 2010, 3,414 in 2011, 6,459 in 2012, and 148,256 in 2013. It is in the National Plan of Integrated Airport Systems for 2011–2015, which called it a general aviation facility.

The first airplane landed at what is now Trenton-Mercer Airport in 1907, in what was then Alfred Reeder's farm field, just off of Bear Tavern Road in Ewing. Twenty-two years later in 1929 Skillman Airport opened to the public.
During World War II the nearby General Motors plant ceased producing civilian vehicles and began making TBF Avenger carrier-based torpedo bombers for the United States Navy. Skillman Airport expanded to accommodate test flights of this aircraft, and after the airport returned to county control following the end of the war it was renamed Mercer County Airport.
For many years the county has planned to expand the airport and attract more commercial airlines. The plans have been opposed by residents of suburban housing tracts in Ewing, Lawrence, Hopewell, Lower Makefield, Pennington and Yardley (some of which are in Pennsylvania, across the Delaware River). Most of these developments were built after the airport.
In 1994 as a cost-cutting measure, the Mercer County Airport Police and Fire Department was disbanded and replaced by the Mercer County Sheriff's Office (police) and ProTec Fire Services (Aircraft Fire Rescue).
Trenton-Mercer Airport has rental cars available in the terminal with no shuttle needed. Enterprise Rent-A-Car and National Car Rental are available 7 days a week from 6am to Midnight.
Avis and Budget car rentals are available at the Ronson Avation FBO with shuttle service from the commercial terminal building. Normal hours of operation are 6:30am to 10:00pm 7 days a week.  
No public transportation options actually pick up or drop off passengers in front of the terminal, but nearby bus and train routes exist. There are no sidewalks, nor shoulders, along the roads that lead to the passenger terminal.
The Trenton-Mercer Airport is within walking distance (1.5 miles) of the West Trenton SEPTA Train Station. This train station serves Philadelphia and points west, but not New York or points east.
On weekdays, NJ Transit's 607 bus stops just outside the airport grounds, at Bear Tavern Rd and Cardinal Dr. The 608 bus, which connects to the Hamilton NJT Train Station and Trenton Transit Center, stops less than a mile from the airport terminal at the intersection of Grand Ave and Upper Ferry Rd (weekdays only).
Civilian Facilities and Aircraft
Trenton-Mercer Airport covers 1,345 acres (544 ha) at an elevation of 212 feet (65 m) above mean sea level. It has two asphalt runways: 6/24 is 6,006 by 150 feet (1,831 x 46 m) and 16/34 is 4,800 by 150 feet (1,463 x 46 m). The airport has three helipads, H1, H2, and H3, each 64 by 64 feet (20 x 20 m). To meet FAA requirements that certain runways be equipped with an EMAS bed before the end of 2013, the airport installed EMAS beds at both ends of runway 16/34 in 2012; officials announced plans in early 2013 to close runway 6/24 for two months that fall to install an EMAS bed at both ends.
In 2010 the airport had 84,614 aircraft operations, an average of 231 per day: 95% general aviation, 3% air taxi, and 2% military. 154 aircraft were then based at this airport: 48% single-engine, 10% multi-engine, 10% jet, 21% helicopter, and 10.4% military.
Civil Air Patrol
Military Facilities and Aircraft
The airport is home to Army Aviation Support Facility #2 and the 1st Battalion, 150th Aviation Regiment, otherwise known as the 1-150th General Support Aviation Battalion of the New Jersey Army National Guard. Equipped with UH-60 Blackhawk helicopters, the battalion provides ground force commanders of the 42nd Infantry Division (Mechanized) with additional air assault, transportation, re-supply, and command and control assets. In its state role under Title 32 United States Code, the unit also provides emergency logistical support in response to disasters or any other emergency support as may be directed by the Governor of New Jersey.
Terminal and future developments
Trenton-Mercer Airport has one terminal with two gates. Trenton-Mercer is served by Enterprise and National on the main floor. On the upper level of the terminal (before security) is an observation lounge as well as a restaurant, Sky Lounge at Ewing, serving pub food. Sky Lounge has another location past security near Gate 1 that serves drinks and pre-packaged sandwiches and wraps. Parking is $2 per hour and $8 per day. On November 8, 2013, Mercer County opened a renovated terminal, including a new modular baggage claim outside the terminal, restrooms in the gate area (there were previously no restrooms past security), and using the space where the baggage claim was to add more passenger seating and an additional gate.
In a study commissioned by the county released in 2013, a new passenger terminal, a corporate office park, medical offices and laboratories, and commercial space would be part of a plan to develop available land at the airport.

- Allegheny Douglas DC-9s nonstop to Chicago in 1977–78 were probably Trenton's first jet flights.
- United flew Boeing 727-200s and Boeing 737s to Trenton in 1984–85.
- In the mid to late 1990s Eastwind Airlines operated a hub out of Trenton to Florida and North Carolina as well as airports in Massachusetts, New York and Pennsylvania. The airline flew from Philadelphia for a short time too. This was one of the only times Trenton-Mercer saw scheduled jet service from its short runways with 737-200 and 737-700 aircraft.
- From 1998 until 2003 Shuttle America operated a scheduled business commuter service to airports in Connecticut, Massachusetts, New York and North Carolina. The airline flew 50 seat De Havilland Dash 8-311 turboprops and had all its aircraft stocked with in-flight service items when stopping in Trenton. The airline ceased operations at TTN after a codeshare service with US Airways drew customers to nearby Philadelphia from Trenton.
- In 2006 and 2007 Comair flew to Atlanta and Boston from Trenton as Delta Connection using CRJ-200 aircraft. After a few months Big Sky Airlines took over the Boston service with Beech 1900s. The service ended in early January 2008.
- From May 2000 until February 2008 Boston-Maine Airways operated the Pan Am Clipper Connection between Trenton-Mercer Airport and Hanscom Field in Bedford, Massachusetts. The flight was terminated when Boston-Maine Airways ceased operating on February 28, 2008.
- On April 4, 2011, Streamline Airlines re-commenced the former Pan-Am Clipper Connection route between Bedford–Hanscom and Trenton using an EMB-120 Brasilia turboprop. The carrier was consistently losing money and shut down on September 14, 2012, citing a poor economic climate and unprofitable operations.
