Traveling with Children

We will always do our best to seat children with an adult family member.  For the best seating options, we recommend booking early and selecting seat assignments at the time of booking or with a reservation crewmember (third party service fees may apply). If seats together are not available, please let our airport gate crewmembers know when you arrive at the airport. They will do their best to find a seating solution. We cannot guarantee that seats together will always be available.

Important Information

  • Infants and children may occupy a seat with or without a child restraint system (CRS). If the infant is not in a child restraint system, they must be able to sit upright.
    • Please note car seat sand child restraint systems are allowed in Mint seats only on A321 Classic Mint (32S) aircraft. They are not permitted in Mint seats on A321 NEO Mint (3NS) or A321 LR (3NL) aircraft.
  • Use of booster seats, harness and vest restraints will not be allowed during the movement on surface (taxiing), take-off or landing, unless it is an FAA-approved device.  
  • Safety seats or CRS should be placed in a window seat. It may be placed in a middle seat or aisle seat as long as the other seat(s) remain empty. 
  • Safety seats may not obstruct a customer’s pathway to the aisle. 
    • Safety seats may not be placed between two individuals. 
    • A safety seat may face backward if it is FAA approved and is properly secured by the parent/guardian. 
  • Any safety seat used during the flight must remain secured to the aircraft seat at all times, even when unoccupied. 
  • Seatbelts must fit low and tight across the waist of all customers, including children. 
    • If used with a CRS, the seatbelt must be affixed to the CRS so that it is secured tightly in the seat. 
    • In seats equipped with an airbag seatbelt, JetBlue-provided seatbelt extensions must be used in conjunction with the seatbelt to secure the CRS. For safety purposes, if the CRS is not able to be properly secured with the airbag seatbelt, the customer may be required to move to a seat with a standard seatbelt in order to use the CRS. 

Family Seating Details

We will always do our best to seat children with an adult family member. Here are some suggestions for the best seating options:

  • Book in advance.
  • Select your seat assignments when you book yourself, or when you book with a crewmember (third party service fees may apply).
  • If there are no seats available together, please inform the airport gate crewmember when you arrive at the airport.

Get informed before you travel:

  • If we automatically assign you to adjacent seats, you will not have to pay any fees.
    • If you change those seats, applicable fees apply.
  • Blue Basic customers are included in the automatic seat assignment.
  • Some conditions must be met before we can attempt to ensure family seating: 
    • Your family members must be on the same reservation.
    • We must have the seating and seating configuration to accommodate it.
For more information on family seating, please see our Customer Service Plan

Baggage Allowance

A child may bring: 

  • Any bags included with the ticket purchase 
  • One stroller  
  • One car seat  

This courtesy is extended regardless of whether the customer is traveling with the infant/child or is meeting the infant/child at their destination. 

Checking a child safety seat will not count towards your checked baggage allowance and there is no fee assessed; however, playpens and other infant beds will count as a checked bag and must meet size and weight requirements. The FAA has more information regarding safety-approved infant/child safety seats on their website.  


Please be aware that strollers are not covered for damage if checked. JetBlue assumes no liability for loss, damage or delay per the JetBlue Airways Contract of Carriage Section 19. 

For passengers traveling on Mint with car seats and child restraint systems, please be aware that these items are not allowed on the A321 NEO Mint (3NS) and A321 LR (3NL) aircraft. The shoulder straps on these aircraft do not accommodate car seats and child restraint systems, making them incompatible for safe use.
