McClellan-Palomar Airport — Carlsbad, United States

North San Diego County relies on CLD for general aviation traffic that would otherwise clog the region's larger commercial fields, plus a modest slate of scheduled flights that give Carlsbad, Encinitas, and other coastal communities a closer alternative to driving into San Diego proper. The airport traces its name to two sources: the McClellan family who once owned surrounding land, and Rancho Palomar, the historic name for the area. A single runway just under a mile long limits operations to smaller regional jets, turboprops, and general aviation aircraft rather than widebodies. Flight schools, corporate aircraft, and charter operators make up much of the daily traffic, while limited commercial service has come and gone over the decades depending on which regional carriers find the short runway and busy Southern California airspace workable for their route economics.
