The Lebanon Municipal Airport accommodates and services a wide variety of commercial and private aircraft, with a 5,000 foot runway and several modern T-Hangers and corporate hangers.

[6] 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 non-hub primary commercial service facility.

At the end of World War II, Sumner Atherton, a veteran aviator, set up Connecticut Valley Airways, and in 1947 he was successful in bidding for a 20-year lease to operate Lebanon Municipal Airport.

The airport was a stop on a daily round trip service operated by Northeast with a Douglas DC-3 linking New York City with Montreal.

In 1964, Northeast was operating direct one stop service to New York John F. Kennedy Airport with four engine Douglas DC-6B propliners via Keene.

According to the April 15, 1975 edition of the Official Airline Guide (OAG), Delta was no longer serving the airport with all flights at this time being operated by Air New England with Beechcraft 99, de Havilland Canada DHC-6 Twin Otter and Fairchild Hiller FH-227 turboprop aircraft with nonstop service to Boston and Montpelier/Barre, VT as well as direct flights to New York LaGuardia Airport via a stop in Keene, NH.
