Trans-Texas Airways (TTa) began their Santa Fe service later in 1963 replacing Continental Airlines at all the stops made on the Albuquerque - Dallas route that Continental acquired from Pioneer Air Lines eight years prior. Initially the carrier used Douglas DC-3 prop aircraft and later upgraded to Convair 600 turboprops. In 1967, TTa had introduced the first jet service into Santa Fe with the Douglas DC-9-10 on nonstop flights to Dallas Love Field with continuing direct service to Houston Hobby Airport. DC-9s were also flown to Albuquerque, Roswell and Midland/Odessa on a flight routing to Dallas and Houston from Santa Fe. Trans-Texas Airways changed its name to Texas International (TI) in 1969 and discontinued DC-9 jet service into Santa Fe by early 1970 but continued to serve the airport with the Convair 600's until June 1972 when both Texas International and Frontier were forced to suspend all flights citing unsafe runway conditions. Neither carrier ever returned.
