West Coast Airlines and its successors Air West, Hughes Airwest and Republic Airlines (1979-1986) served the airport for many years. In 1954, West Coast was serving Twin Falls with nonstop Douglas DC-3 flights to Boise and Burley/Rupert with direct service to Pocatello and Idaho Falls as well as connecting flights to Portland, OR and Seattle Boeing Field.  By 1960, West Coast was operating Fairchild F-27 turboprops into the airport with nonstop flights to Boise and Salt Lake City and also direct, no change of plane F-27 service to Seattle Boeing Field.  In 1968, West Coast merged with Bonanza Air Lines and Pacific Air Lines to form Air West which in turn continued to serve Twin Falls. Air West was operating Fairchild F-27 propjet service into the airport in 1968 with nonstop flights to Boise and Salt Lake City as well as direct, no change of plane flights to Phoenix and Spokane.  According to the July 1, 1968 Air West system timetable, Twin Falls was even receiving international service of a sort at this time as the airline was operating a direct F-27 flight from Calgary into the airport via intermediate stops in Spokane, Boise and other small cities in the region. Air West then changed its name to Hughes Airwest which in turn continued to serve Twin Falls.
The jet age arrived in Twin Falls during the early 1970s. In 1972, Hughes Airwest was operating all flights into the airport with Douglas DC-9-10 and McDonnell Douglas DC-9-30 jets with nonstop service to Boise and Salt Lake City as well as direct, no change of plane DC-9 flights to Los Angeles ( LAX), Las Vegas, Seattle, Spokane, Burbank and other destinations.  The July 1, 1972 Hughes Airwest system timetable stated that Twin Falls was the "jet gateway" for the Sun Valley, Idaho summer and ski resort area as the Friedman Memorial Airport (SUN) serving Sun Valley did not have airline jet flights at this time and was only served by commuter air carriers operating turboprop and prop aircraft during the 1970s. By 1975, Hughes Airwest was continuing to operate all flights into Twin Falls with DC-9-10 and DC-9-30 jets with nonstop service to Boise, Salt Lake City, Stockton and Pocatello in addition to direct flights to San Francisco ( SFO), Los Angeles ( LAX), Orange County, Las Vegas, Seattle, Portland, OR, Spokane and Idaho Falls.  During the ski season in early 1976, the airline had added nonstop DC-9 flights between Twin Falls and both Los Angeles ( LAX) and San Francisco ( SFO) which were operated only on Saturdays.  According to the February 1, 1976 Official Airline Guide, Hughes Airwest was the only airline operating jet service into Twin Falls at this time with eight DC-9 jet flights a day operated to the airport on Saturdays with a lesser number of jet flights operated on other days of the week.  This same OAG also lists direct, no change of plane DC-9 flights operated from Los Angeles, San Francisco, Las Vegas, Seattle, Portland, OR, Santa Ana/Orange County, Santa Barbara, Spokane, Idaho Falls and Lewiston, ID in addition to daily nonstop DC-9 flights from Boise, Salt Lake City, Stockton, CA and Pocatello. In 1980, the airline was still operating DC-9 jet service nonstop to Boise and Salt Lake City with one stop direct flights to Burbank, Phoenix and Portland, OR as well as direct, no change of plane DC-9 flights to Seattle, Spokane and Tucson. 
Hughes Airwest was then acquired by and merged into Republic Airlines (1979-1986) which continued to serve Twin Falls. In 1982, Republic was operating DC-9 jet service from the airport nonstop to Boise, Salt Lake City and Pocatello with direct, no change of plane flights to Seattle, Spokane and Burbank.  By 1984, Western Airlines was serving Twin Falls on a seasonal basis with nonstop flights to Los Angeles ( LAX) operated with Boeing 737-200 jetliners.  However, by 1985 both Republic and Western had ceased serving Twin Falls and the airport no longer had jet service at this time. 
Several commuter air carriers also served Twin Falls over the years. In the early 1970s, Trans Magic Airlines (TMA), which was based in Twin Falls, was operating a hub at the airport with flights to Boise, Burley, ID, Coeur d'Alene, ID, Idaho Falls, Jackpot, NV, Lewiston, ID, McCall, ID, Mountain Home Air Force Base, Moscow, ID, Pocatello, Pullman, WA, Salt Lake City and Sun Valley, ID with this commuter airline flying de Havilland Heron four engine prop aircraft and Piper Navajo twin engine prop aircraft.  By 1974, Air Idaho was operating a small hub at the airport with nonstop service to Boise, Burley, Elko, NV, Salt Lake City and Sun Valley flown with de Havilland Heron aircraft.  In 1976, another commuter air carrier, Sun Valley Key Airlines, was serving Twin Falls with flights from Salt Lake City and Pocatello operated with Piper Navajo prop aircraft while Air Idaho was continuing to operate flights from Salt Lake City and Sun Valley with the de Havilland Heron.  Cascade Airways briefly served Twin Falls in 1980 with nonstop flights to Boise and Salt Lake City operated with Embraer EMB-110 Bandeirante commuter turboprops.  In 1981, Mountain West Airlines-Idaho was operating nonstop flights to Boise with Embraer EMB-110 Bandeirante turboprops.  Skywest Airlines began serving Twin Falls as an independent commuter airline during the early 1980s and by 1983 was operating nonstop flights to Salt Lake City and Pocatello with Swearingen Metro III commuter propjets.  Also in 1983, Transwestern Airlines was operating nonstop flights to Boise and Salt Lake City with Swearingen Metro III commuter propjets.  Later in 1983, Transwestern was then acquired by and merged into Horizon Air which in turn continued to operate nonstop flights to Boise and Salt Lake City with Swearingen Metro III propjets. In 1987, SkyWest Airlines was operating as Western Express on behalf of Western Airlines via a code sharing agreement with nonstop flights to Salt Lake City and Pocatello operated Swearingen Metro III propjets.  Western was then acquired by and merged into Delta Air Lines later in 1987 with SkyWest then becoming a Delta Connection air carrier via a code sharing agreement with Delta and this business relationship between the two airlines has been in effect since that time. In 1994, there were two airlines serving Twin Falls: Horizon Air operating code share service on behalf of Alaska Airlines with nonstop Swearingen Metro III service to Boise and SkyWest operating Delta Connection service nonstop to Salt Lake City with Embraer EMB-120 Brasilia propjets.  By 1999, SkyWest flying as the Delta Connection was the only airline serving Twin Falls and was continuing to operate nonstop Embraer EMB-120 Brasila flights to Salt Lake City.  SkyWest is currently the only airline operating scheduled passenger flights from the airport and has served Twin Falls for 35 years.
