At Jetstar we refer to children under 2 years old as infants.

  • If you’re happy to nurse your infant on your lap, they can travel for free on all domestic flights within Australia, Japan, Vietnam and New Zealand, and international flights between Australia and New Zealand.
  • On all other Jetstar flights, infants not occupying a seat travel for a small fee.
  • Your infant can sit on your lap for the entire flight. You’ll be provided with a special seat belt for your infant that connects to your seatbelt. If you’re nursing an infant, or if you're travelling with a child, you won’t be able to travel in an exit row seat (this includes extra legroom seats).
  • If your infant is less than 2 years old on your outbound flight, they won’t need an allocated seat on the return flight, even if they turn 2 during your trip. This won’t apply if your infant was booked on separate bookings for the outbound and return flight.
  • You can purchase a separate seat for your infant, but they must be able to sit up unaided. On all Jetstar aircraft other than our Q300 (domestic New Zealand only) you can bring an approved car seat for them to sit in. See: What do I need to know about bringing a car seat on board? You must contact us if you’re bringing a car seat, as a limited number can be fitted on each flight. Car seats must be fitted onto a window seat.
  • Children aged 2 years or older must travel in an allocated seat for safety reasons, so you’ll need to purchase a fare for them.
  • Passengers must be at least 15 years old to sit in exit rows. This includes all extra legroom seats.

Travelling with more than one infant

A single passenger may accompany two infants. One infant can be nursed on the passenger's lap, but the second infant must have an allocated seat and be sitting up unaided or in an approved car seat. Make sure you contact us if you’re bringing a car seat, as numbers per flight are limited. Make sure you also contact us if you’re travelling with more than one infant.

Infants and accompanying passengers

Infants over 3 months old must be accompanied by someone who’s 15 years or older, self-reliant and capable of looking after them, both at the airport and during the flight.

Infants less than three months old must travel with a parent or legal guardian.

Infants less than 7 days old

Infants less than 48 hours old are not permitted to travel on Jetstar flights.

A Jetstar medical clearance form must be completed for infants aged between 3 and 7 days old for them to travel on Jetstar (JQ), Jetstar Asia (3K) and Jetstar Japan (GK) flights. No infant less than 7 days old may travel with Jetstar Pacific (BL).

Bassinets can be requested on some international flights. See: Can I request a bassinet for my infant?

Checking in

If you're travelling with an infant you can't check in online, you must check in at the airport. See: Can I check in online?


Proof of age, such as a birth certificate or passport, may be required for infants under 2 years. If you don’t provide an acceptable form of identification for the infant upon request at check-in, your infant may not be allowed to travel.

If you’re travelling on an international flight, your infant or child always requires a passport.

Infant food and drink

We don’t carry infant food or drinks on board, so be sure to bring enough of both with you. It will count towards your carry-on baggage allowance. See: Do I need to bring food and drinks for my infant?

Infants and carry-on baggage

Infants not occupying a seat don’t have a carry-on baggage allowance.

You’ll have to carry any baby items such as food, drink, nappies and clothing as part of your own carry-on baggage allowance.

If your infant has an allocated seat, and is either sitting up unaided or in an approved car seat, their fare includes the standard carry-on baggage allowance.

Infants and checked baggage

We know that travelling with infants and small children requires a lot of gear, so we let you carry a pram, a stroller, a portable cot and a highchair as checked baggage for free, regardless of fare and in addition to any checked-baggage allowance.

See: Can I bring a pram, stroller, portable cot or highchair as checked baggage?

Infants not occupying a seat are not entitled to a checked baggage allowance.

Infant harnesses and slings

Harnesses and slings are handy at the airport, but their use is restricted on board. See: Can my infant travel in a baby carrier or harness?
