The JetBlue flight change policy is designed to provide travelers with flexibility when adjusting their travel plans. Most fare types allow changes without a fee, though a fare difference may apply. Blue Basic fares are more restrictive and may not qualify for free changes. Same-day flight changes are available for a small fee and depend on seat availability. Refundable fares offer the highest level of flexibility, allowing free modifications. It’s important to make any changes before the flight\'s departure to avoid losing ticket value. Understanding your fare conditions can help avoid extra costs and make trip adjustments stress-free.
