JSX Scales Up ATR 42-600 Fleet to Reach Short-Field, High-Altitude Airports

Overview

• JSX confirms it will operate four ATR 42-600s in early 2026, each configured with 30 all-premium seats.
• The first ATR 42-600 entered service in December on the Santa Monica–Las Vegas route, marking JSX’s debut use of turboprops.
• ATR received U.S. approval for a high-altitude avionics modification, enabling operations at airports up to 11,000 feet.
• The ATR 42-600’s short-runway performance gives JSX access to smaller airports that its Embraer E135/E145 jets cannot serve.
• ATR and JSX showcased the aircraft at a January 12 Santa Monica event, and JSX holds options for up to 25 additional units.
