JSX launches ATR 42-600 operations as it expands U.S. public charter network

JSX, a U.S. public charter carrier that markets itself as a “hop-on” service using private terminals and streamlined ground procedures, held a ceremonial event at Santa Monica Airport to highlight the entry into service of its first ATR 42-600. The aircraft, however, had already entered revenue service in December on the Santa Monica–Las Vegas route.

The airline plans to operate four aircraft in early 2026, each configured with 30 seats in a premium layout. The turboprops are intended to complement JSX’s existing jet fleet by enabling access to smaller and more operationally challenging airports.

The ATR 42-600 will be used to support JSX’s semi-private public charter model, offering business-class legroom, power outlets and onboard connectivity, subject to certification. According to the airline, the aircraft allows it to expand its network to airports that are not practical for larger regional jets, while maintaining its existing service concept.

ATR views the partnership as a potential entry point for wider adoption of turboprops in the U.S. regional market, particularly as older 50-seat regional jets are retired, although the U.S. airline market has remained largely reluctant to return to regional turboprop operations in recent years.

To support JSX’s network plans, ATR recently secured FAA approval for a modification enabling operations at high-altitude airports, a capability seen as key to expanding service across the Mountain West. The approval allows the aircraft to operate more efficiently in performance-limited environments.

The partnership between ATR and JSX was formalized at the 2025 Paris Air Show, where the two companies signed a letter of intent covering up to 25 ATR aircraft in a high-end interior configuration. JSX currently operates a fleet dominated by Embraer regional jets and has indicated that the ATR will play a complementary role rather than replace its jet operations.
