Manchester–Boston Regional Airport

Manchester–Boston Regional Airport (IATA: MHT, ICAO: KMHT, FAA LID: MHT), informally referred to by its former name Manchester Airport, is a public use airport 3 miles (5 km) south of the central business district of Manchester, New Hampshire, United States on the border of Hillsborough and Rockingham counties. It is owned by the city of Manchester, and is in the southern part of the city on the border with Londonderry, New Hampshire.

Opened in 1927, Manchester–Boston Regional Airport is by far the busiest airport in New Hampshire, with ten times the traffic of the next-busiest, Portsmouth. It is the only airport in the state with substantial commercial service. It is also New England's sixth-largest airport by passenger volume, behind Logan in Massachusetts; Bradley in Connecticut; Rhode Island T. F. Green in Rhode Island; Portland in Maine; and Patrick Leahy Burlington in Vermont. It moved more than 1 million passengers in a year for the first time in 1997. After years of growth, it handled 4.33 million passengers in 2005, its peak year. Passenger tallies have declined since then, similarly with many regional airports; it handled 1.85 million passengers in 2018, and traffic fell sharply during the COVID-19 pandemic.

It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2021–2025, in which it is categorized as a small hub primary commercial service facility. The facility was known as Manchester Airport until April 18, 2006, when it added "Boston Regional" to advertise its proximity to Boston, about 50 miles (80 km) to the south. The airport has a Cat III B Instrument Landing System. It is home to the Aviation Museum of New Hampshire, built around an Art Deco control tower, and its terminal opened in 1938.
