JSX typically operates nonstop flights from smaller airports to popular destinations like Las Vegas' Harry Reid International Airport. The airline uses private terminals and offers amenities commonly found only in premium lounges, including complimentary snacks and drinks.
Operating under a public charter certification allows JSX to fly aircraft with up to 30 seats at lower costs compared to larger regional carriers such as Republic Airlines and SkyWest Airlines. Investors in JSX include JetBlue, Qatar Airways, and United Airlines. The company has partnerships with JetBlue and United and launched its own loyalty program, Club JSX, in July.
Currently, JSX's fleet consists entirely of Embraer ERJ regional jets.
Wilcox explained that the introduction of ATR-42s would allow access to more markets at reduced costs for the airline. "From my perspective the plane is half, half and double," he said. "The ATR needs half the runway, burns half the fuel and doubles the number of airports JSX can serve compared to the airline's Embraer jets." Alexis Vidal, chief commercial officer of ATR, added that their turboprops are approximately 30% less expensive to operate than 50-seat regional jets.
Turboprops once played a significant role in U.S. regional aviation but were largely replaced by faster regional jets beginning in the 2000s. Rick Leach, CEO of GoJet Airlines—a United Airlines affiliate—commented on this shift: "We've spoiled the public with the regional jet and what it does." He also noted that despite perceptions of propeller planes being outdated technology, modern turboprops often surpass regional jets technologically.
Alaska Airlines' subsidiary Horizon Air was among the last major U.S. carrier affiliates to operate turboprops before retiring its Bombardier Dash 8-Q400 fleet in January 2023.
Addressing whether premium travelers would accept flying on turboprops, Wilcox remarked: "I guess [you've] never been to St. Barts," referencing Gustaf III Airport which is exclusively served by turboprop aircraft.
JSX’s initial commitment involves leasing two ATR-42s previously operated by Silver Airways for launch later this year; two additional leased planes are expected early next year. "We need to prove that our customers will get on a turboprop airplane," Wilcox said. "For the reasons I already outlined — because it's going to be so much more convenient to them, because the airports we're going to choose for it are so much closer to where they live and where they want to go — I'm supremely confident it's going to happen but we still need to prove it before we can put real money behind it."
If successful, JSX may proceed with plans outlined earlier this year for up to 25 new ATR aircraft—potentially expanding service across its U.S. network and enabling access to hundreds more airports than currently served.
