Newport State Airport covers an area of 540 acres (220 ha) which contains two asphalt paved runways (5/23 and 18/36), each measuring 4,000 x 100 ft (1,219 x 30 m).
For the 12-month period ending August 18, 1997, the airport had 7,140 aircraft operations, an average of 19 per day: 97% general aviation and 3% military. There are 17 aircraft based at this airport: 88% single engine and 12% multi-engine.
Until the 1970s, Newport city owned the airport. They sold it to the state of Vermont.
On August 14 - August 15, 2004 the airport served as the site of Coventry, the former final live concert appearance by the musical group Phish, attended by tens of thousands of fans.
On January 9, 2012 the state announced its intention to seek Federal approval for an expansion. The project, projected to take 9 years would extend the runway by 1,000 to 5,000 feet (300 to 1,520 m) with the capability of handling private jets. Other improvements include expanded water and sewer services, a new terminal, new taxiways, and services from the U.S. Customs and Border Protection and the Transportation Security Administration. 
In 2013, Flight Design announced the intention of assembling CTLS planes at the airport from nine pieces, fabricated in Germany. It would employ about 35 workers.
