Trans World Airlines, (TWA), began Santa Fe service in 1948 by adding the city as a stop on its transcontinental mainline route using Douglas DC-3 aircraft. Initially the daily routing was New York LaGuardia Airport - Pittsburgh - Columbus, OH - Dayton - Chicago Midway Airport - Kansas City - Topeka, KS - Wichita - Amarillo - Santa Fe - Winslow, AZ - Phoenix - Los Angeles. Albuquerque was later added as stop on the way to Winslow and the Martin 4-0-4 aircraft replaced the DC-3s. By 1959, TWA was operating four engine Lockheed Constellation propliner service into Santa Fe with a daily routing of Chicago Midway Airport - Kansas City - Wichita - Amarillo - Santa Fe - Albuquerque - Los Angeles but only in the westbound direction. TWA's service to Santa Fe ended by late 1960.
