JSX and similar charter operators are exploiting regulatory gaps to offer scheduled service with the perks of private aviation—assigned seating, minimal TSA friction, premium cabins—at prices that approach budget carriers but bypass their safety and labor requirements. Traditional airlines are pushing back because semi-private operators occupy a regulatory blind spot: they operate under Part 135 charter rules rather than Part 121 commercial carrier standards, allowing them to avoid unionized crews, full crew rest requirements, and other cost drivers that make legacy carriers uncompetitive on thin routes like Boston-Miami.
