Dillant Hopkins Airport — Keene, United States

EEN, Dillant-Hopkins Airport, serves Keene in southwestern New Hampshire. Named for local aviation figures, the airport supports general aviation, corporate flights, flight training, and occasional charter operations for the Monadnock region, home to Mount Monadnock and a cluster of small New England towns. EEN has historically seen limited scheduled airline service attempts, though it functions mostly as a general aviation facility today. The airport includes hangar space, a paved runway suitable for regional jets and turboprops, and serves as an access point for businesses and residents in the Keene area who would otherwise face long drives to Manchester or Boston airports. Its role fits the broader pattern of small New England airports supporting rural connectivity.
