It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021, 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 to the south. Certified for Cat III B Instrument Landing operations, the airport has a reputation for never surrendering to bad weather. The airport has closed only once, when the national airspace was shut down for two days following the September 11 terrorist attacks, and all American airports were required to close. It is home to the Aviation Museum of New Hampshire, built around an Art Deco control tower and terminal opened in 1938.
