[1] American, Braniff, Central, Continental, Delta, Eastern, Frontier, and Trans-Texas Airways operated from the airport, which had three paved runways and an elaborate terminal (with gold-plated murals).

American Airlines was operating Boeing 727-100 service into Greater Southwest twice a day with a westbound flight routing of New York LaGuardia Airport - Chicago O'Hare Airport - Fort Worth - El Paso - Los Angeles and an eastbound flight routing of Los Angeles - El Paso - Fort Worth - Oklahoma City.

[8][9] Braniff International also flew nonstop service between GSW and Houston Hobby Airport operated with British Aircraft Corporation BAC One-Eleven twinjets and Lockheed L-188 Electra turboprops.

In 1968, Braniff International was operating a "milk run" flight serving the airport every weekday with a Lockheed L-188 Electra turboprop flying a westbound and then southbound routing of Memphis, TN - Little Rock, AR - Fort Smith, AR - Tulsa, OK - Dallas Love Field - Fort Worth - Houston Hobby Airport - Corpus Christi, TX.

[12] By the fall of 1967, Central had been acquired by and merged into the original Frontier Airlines (1950-1986) which continued to operate just one departure a day from the airport on the same round trip "milk run" routing between Fort Worth and Kansas City flown with a Convair 580 turboprop.

By the late 1960s, Continental was operating Douglas DC-9-10 jet service into the airport with one flight each way on a Dallas Love Field - Fort Worth - Midland/Odessa - El Paso routing.

[14] Delta was serving the airport during the mid 1960s with a Convair 440 twin prop "milk run" flight on a westbound routing of Charleston, SC - Columbia, SC - Atlanta - Columbus, GA - Montgomery, AL - Jackson, MS - Monroe, LA - Shreveport - Dallas Love Field - Fort Worth with this service then changing flight numbers at the airport and making the short hop back to Love Field.

[15][16] Eastern Airlines with direct, no change of plane Boeing 727-100 jet service to New Orleans, Tampa and Orlando via a first stop at Dallas Love Field.

[27] The federal National Transportation Safety Board (NTSB) determined that wake turbulence from another training flight, an American Airlines DC-10 widebody jetliner, had caused the Delta DC-9-14 twin jet to lose control as it neared touchdown.
