JetBlue recently introduced a formal Family Seating Guarantee to ensure that children aged 13 years and younger can sit next to an adult traveling with them on the same reservation. The guarantee incorporates a new process that proactively identifies reservations with children and adults traveling together without prior seating assignments. For no additional fee, the process will ensure a traveling child is assigned a seat next to at least one accompanying adult when seats are available.  For bookings made within 24 hours of planned travel, seats may need to be assigned manually by a JetBlue airport crewmember. The airline is urging you to continue to proactively select your seats at the time of booking to ensure the smoothest travel experience possible.
