The United States Court of Appeals for the Third Circuit has dismissed a suit filed by a group of activists seeking to overrule the Federal Aviation Administration's (FAA) decision to allow Allegiant Air (G4, Las Vegas Harry Reid) to operate out of Trenton, NJ.

The petitioners, who mostly reside in neighbouring Pennsylvania rather than in New Jersey, argued that the FAA did not properly consider noise impact that Allegiant Air's operations will have on the airport's surroundings. In its ruling issued on January 9, 2018, the court, however, found that the FAA had correctly assumed that even based on the long-term air traffic projections, operations out of Trenton, NJ, will not "significantly affect the quality of the human environment" and thus do not require a detailed impact assessment.

Allegiant Air applied to the FAA in 2016 for a change to the airport's operating specifications which would allow the carrier to operate up to 7 round trips per week. The regulator granted the request in November 2016, prompting the appeal by the local activists.

According to the ch-aviation capacity module, the ULCC currently flies out of Trenton 2x weekly to Punta Gorda, FL. It is a minor player at the airport compared to Frontier Airlines which operates 36 weekly departures.
