Niort - Marais Poitevin Airport — Niort/Souché, France

NIT serves Niort - Marais Poitevin Airport, located at Souché near Niort in western France, close to the Marais Poitevin wetlands, one of France's largest marshland nature reserves. The airport is a small regional facility primarily used for general aviation, flight training, and limited seasonal or charter flights rather than major scheduled airline routes. Niort itself is known as an insurance industry hub, hosting headquarters of several French insurance companies, and NIT has occasionally supported business travel connected to this sector. The airport's modest single runway and terminal reflect its role as a regional gateway rather than an international one, with most travelers to the area typically arriving via larger airports like La Rochelle or Poitiers.
