Requirements for bringing a lap child

Lap children traveling within the U.S.

Customers traveling with a lap child may add this information to their reservation when booking online at If you would like to add a lap child to an existing reservation, please call us at 1-800-JETBLUE (538-2583). Customers who are deaf or hard of hearing or who have a speech disability can call our toll-free TTY/TDD telephone number, 711.

A child between the ages of three days old until their second birthday is considered a lap child and does not need to pay for a seat.

Once a child has their second birthday, they are no longer considered a lap child and a seat must be purchased in order for them to travel. If the child has their second birthday between the outbound and return flight, a seat will need to be purchased for the return flight.

Customers traveling with a lap child will be asked for proof of age, such as a passport, birth certificate (copies are acceptable for domestic travel) or an immunization record. Infants between three and 14 days old must also have, in the form of a letter, their doctor's approval to travel.

Infants must be traveling with an adult customer at least 14 years or older, and the infant must sit on the adult's lap during takeoff and landing.

One lap child per adult is allowed. Due to the number of oxygen masks per row, only one lap child is allowed per row of three seats for A321 Core, A320 and E190. The number of lap children per row for A321 Mint is not limited by the number of oxygen masks. In cases of flights that are extended over-water flights, due to the number of spare life vests, JetBlue may have to limit the number of lap children on the flight

A lap child may bring one (1) diaper bag and one (1) stroller and car seat. They do not qualify for the checked baggage allowance.

Customers traveling with a lap child may check in at a JetBlue ticket counter, kiosk or online check-in. However, proof of age will be requested, including a birth certificate, passport or immunization record.

Baggage requirements for infants

A lap infant may bring one (1) diaper bag, one (1) stroller and one (1) car seat. Lap infants that are traveling at no cost do not qualify for the checked baggage allowance.

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.

FAA-approved infant/child safety seats

JetBlue allows the use of FAA-approved infant safety seats secured to standard aircraft seats. Safety seats must have the appropriate manufacturer's label.

Child Restraint Systems (CRS) manufactured between January 1, 1981 and February 25, 1985 must have one of the following labels: "This child restraint system conforms to all applicable federal motor vehicle safety standards." Or "This restraint is certified for use in motor vehicles and aircraft."

Seats manufactured after February 26, 1985 must have an additional label which reads: "This restraint is certified for use in motor vehicles and aircraft."

Booster-type seats, vest and harness-type child restraint systems, lap-held child restraints or seats manufactured before January 1, 1981 are not acceptable.

Guidelines for using child restraint systems (CRS) and child safety seats aboard a JetBlue flight
  • 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.
  • 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, including harnesses or other restraint systems, 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 or occupied by another infant seat. 
  • 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 properly secured by the parent/guardian.
  • Any safety seat used during 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.
  • Only one lap infant will be assigned per row of seats on each side of the aircraft.
  • Lap infants may not be seated in emergency exit rows. 

Please note that JetBlue does not provide CRS, safety seats, child aviation restraint systems (CARES), nor the bags/boxes to cover them.

All special accommodations are left to the discretion of the Inflight crewmembers.
