JSX contact information

Customer Support

• Phone: (800) 435-9579 - Use this for time-sensitive issues such as flight changes, missed check-ins, or baggage problems.
• Email: [email protected] - Best for non-urgent inquiries, booking questions, and detailed requests that you want documented.
• Website: www.jsx.com - Visit for flight search, booking, fare information, and account management (Club JSX frequent-flyer program).

For most queries-baggage limits, special requests, or booking changes-email is reliable and provides a record. Call during business hours if you need immediate assistance with a departure-day issue. The website is the primary channel for real-time flight schedules and online booking.
