Public transportation extensions to airports have often focused on the needs of air travelers; the employee market has generally received less attention in ground transportation planning at airports. An extension of a local New York City Transit Authority bus route, the Q3, into John F. Kennedy International Airport (JFK) is described, and the results of a survey of Q3 riders are presented. JFK employees form a stable ridership base, and those recently employed are especially dependent on Q3 service. The route extension has been successful in attracting new riders from alternative modes (primarily the automobile). Free transfer privileges with connecting bus routes have been instrumental in establishing a large service area for local bus service to JFK.
