A child over three days old until their second birthday is considered a lap child and does not need to pay for a seat. JetBlue does not reserve a seat for these children unless a separate seat is purchased.

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 may be required to present the infant's passport to a JetBlue crewmember at the airport in order for the infant to jet. In addition to the country-specific documentation requirements outlined below, infants between three and 14 days old must also have, in the form of a letter, their doctor's approval to travel.

Customers traveling with lap infants and departing from international destinations to the U.S. will be assessed a $12 infant fee.

• All infants/lap children must be booked at the airport where they will collect any required infant fee.
• Lap infants must be traveling with an adult customer at least 14 years of age or older, and the infant must sit on the adult's lap during takeoff and landing.
• Only 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.
• A lap child may bring one diaper bag, one stroller and a car seat. They do not qualify for the checked baggage allowance.

Strict exit requirements apply to minors under 18 years of age (of any nationality) who are residents in the Dominican Republic. Such children traveling alone, without both parents, or with anyone other than the parent(s), must present written authorization from a parent or legal guardian. This authorization must be in Spanish, and it must be notarized at a Dominican consulate in the United States or notarized and then certified at the Dominican Attorney General’s office (Procuraduria de la Republica) if done in the Dominican Republic. Though not a requirement for non-resident minors (in the Dominican Republic), the U.S. Embassy recommends that any minor traveling to the Dominican Republic without one or both parents have a notarized document from the parent(s).

This letter of authorization must:

• Be written in Spanish;
• Contain the name of the child, the parent or legal guardian, and, if applicable, the adult accompanying the child; and

Infants and children may occupy a seat with or without a child restraint system. 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, takeoff or landing, unless it is an FAA-approved device.

If checking a safety seat, it will not count as one of your checked bags and there is no fee assessed.

Child aviation restraint systems (CARES) are also certified by the FAA for use during all phases of flight including taxiing, takeoff, landing and during periods of turbulence. CARES is a belt-and-buckle device that attaches directly to the aircraft seatbelt. It is designed for children over one year old, weighing between 22 and 44 pounds.

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

In addition, the following guidelines will be observed:

• an infant safety seat cannot occupy an exit row seat nor an aisle seat.
• an infant safety seat should be placed in a window seat; it may be placed in a middle seat as long as the window seat remains empty.
• infant safety seats may not be placed between two individuals.
• only one lap infant will be assigned per row of seats on each side of the aircraft.
• any infant seat used during flight must remain secured to the passenger seat at all times, even when unoccupied.
