Steps to Book a JSX Airlines Flight Online:

• Visit the JSX Website or App: Go to jsx.com or download the JSX mobile app (available on iOS and Android). Select “Book” from the homepage or app interface.
• Enter Flight Details: Input your departure city, destination (e.g., Dallas to Las Vegas), travel dates, and number of passengers. Choose “One-way” or “Round-trip” as needed. JSX displays available flights, operated on 30-seat Embraer jets with 36-inch seat pitch [‽web:5].
• Select Your Flight and Fare: Choose your preferred flight and fare type: “Hop On” (basic fare, includes two checked bags, $50 change fee) or “All In” (flexible fare, includes three checked bags, no change fees, free seat selection). Fares typically range from $159–$300 one-way for domestic routes (e.g., $159 for Las Vegas to Burbank if booked early) [‽web:5, ‽web:13].
• Provide Traveler Information: Enter traveler details, including full name, date of birth, and passport information for international flights (e.g., to Cabo San Lucas, Mexico, requiring a passport valid for 6 months). Ensure details match ID or passport to avoid boarding issues [‽web:0].
• Complete Payment: Add extras like pet travel ($100 one-way, limited to five pets per flight) or additional baggage, if needed. Apply promotional codes (e.g., “Z77HO3” for $100 off your first flight, if available) [‽web:10]. Pay with a credit card and confirm the booking to receive a confirmation email with your itinerary [‽web:5].

Key Considerations:

• Booking Window: JSX allows bookings up to 11 months in advance (through mid-June 2026 as of August 21, 2025, 6:19 PM IST). Booking 1–3 months ahead for domestic flights or 3–5 months for international routes can save $50–$150 compared to last-minute fares [‽web:5].
• Fares and Costs: “Hop On” fares start at $159 one-way for domestic routes, with “All In” fares slightly higher. Check jsx.com’s fare calendar for cheaper days like Tuesdays or Wednesdays [‽web:13].
• Change Policy: “Hop On” fares incur a $50 fee for changes, with the remaining value as a credit valid for one year. “All In” fares have no fee, with refunds to the original payment method or credit. All fares are changeable within 24 hours of booking for no fee if booked at least 24 hours before departure (e.g., booked today, August 21, 2025, at 6:19 PM IST, changeable by August 22, 2025, at 6:19 PM IST) [‽web:13].
• Baggage: “Hop On” fares include one carry-on (13” x 11” x 17”, fits under the seat) and two checked bags (up to 50 lbs each); “All In” fares include three checked bags. Overweight bags incur additional fees [‽web:0].
• International Flights: JSX operates select routes to Mexico (e.g., Cabo San Lucas). Verify entry requirements (e.g., passport valid for 6 months) by calling ☎️＋1 844-734-0813. Online check-in is not available; check in at the airport 20 minutes before departure (with bags) or 15 minutes (without) [‽web:0].
• Loyalty Programs: Earn JetBlue TrueBlue points (250 for “All In,” 150 for “Hop On”) or United MileagePlus miles (50–100% of miles flown) by adding your frequent flyer number during booking [‽web:10].
• Travel Agency Bookings: Book through agencies like Alternative Airlines (alternativeairlines.com) for flexible payment options, but direct bookings on jsx.com are recommended for simplicity. Confirm by calling ☎️＋1 844-734-0813 [‽web:0].
