Braniff began serving Fort Smith with Douglas DC-3 aircraft flying a daily round trip routing of Denver-Colorado Springs-Pueblo-Amarillo-Oklahoma City-Tulsa-Muskogee, OK-Fort Smith, AR-Little Rock-Memphis, TN[4] and later operated Convair 340 and Convair 440 propliners as well as Lockheed L-188 Electra turboprops and British Aircraft Corporation jets followed by Boeing jetliners into the airport.

In 1952, four engine Douglas DC-4 aircraft were flown on the interchange service with a daily routing of Denver-Amarillo-Oklahoma City-Tulsa-Fort Smith-Little Rock-Memphis-Birmingham-Atlanta-Tampa-Miami with the return flight from Miami making an additional stop in Colorado Springs before arriving into Denver.

[7] In 1967, the two airlines were continuing to operate this interchange service between Denver and Atlanta with Lockheed L-188 Electra turboprops; however, these flights were no longer serving Fort Smith by this time.

[9][10] In the spring of 1966, the airline was serving the airport with two BAC One-Eleven jet flights a day on a daily roundtrip routing of Minneapolis/St.

Paul-Omaha-Kansas City-Tulsa-Fort Smith-Shreveport-New Orleans in addition to operating services on other routes from Fort Smith with Convair propliners.

Mid-Continent Airlines began service to Fort Smith in 1946, flying a daily round trip routing of Kansas City-Joplin-Tulsa-Muskogee, OK-Fort Smith-Texarkana-Shreveport-New Orleans with Douglas DC-3 aircraft.

Central Airlines began service to Fort Smith in the mid 1950s with flights on routings of Tulsa-Fort Smith-Hot Springs, AR-Little Rock and Ft. Worth-Dallas-Paris, TX-Fort Smith-Fayetteville, AR-Joplin-Kansas City.

The Fayetteville-based airline, which was also known as Skyways, subsequently added new flights from Fort Smith to Dallas/Fort Worth (DFW), Kansas City, Little Rock, Memphis, St. Louis, Tulsa and other regional destinations in the early 1980s as Frontier ended their respective flights with Skyways operating Nord 262 turboprops on some services in addition to the Metroliner propjets.

British Aerospace BAe Jetstream 31 and Saab 340 turboprops were first used and with service then upgraded to Canadair CRJ-200 regional jets in the mid 2000s.

Atlantic Southeast Airlines (ASA) then resumed the Delta Connection service to DFW flying Embraer EMB-120 Brasilia turboprops from late 1986 until mid 2001.

[27] On September 1, 2015, Delta Connection switched to using Canadair CRJ-700 regional jet aircraft featuring first class as well as coach seats.
