How Old Must a Baby Be to Fly to Bali?

Most airlines let a baby fly without extra paperwork from about 7-8 days old; every airline we checked refuses babies under 48 hours, and days 3-7 need a doctor's letter or medical clearance. Citilink is the strictest: under 8 days is refused, and a doctor's letter is required up to 20 days. Figures below were checked in October 2026 on official airline sites; some sites block direct access, so we read their page text via search results. Double-check when you book.

Minimum age by airline

• Garuda Indonesia: under 48 hours refused. Days 2-7 need medical and release forms plus head-office approval. From 7 days, no extra documents.
• Lion Air: may refuse babies under 2 days. Days 3-7 need a doctor's letter issued within 72 hours of departure (conditions of carriage, 17 April 2026).
• Batik Air: days 3-7 need a doctor's letter (valid 3 days) and a declaration form; 8 days to 6 months need the declaration only. Batik's Malaysia page says "over 8 days", so pages disagree.
• Citilink: under 8 days refused; days 8-20 need a doctor's letter; from 21 days no letter. Another FAQ page gives different numbers, so go by the stricter limit.
• AirAsia (including Indonesia AirAsia): may refuse babies 8 days or younger unless there is medical approval and a signed liability statement.
• Jetstar: under 48 hours refused; days 3-7 need medical clearance.
• Qantas: under 48 hours is too young; days 3-7 need a medical clearance form that takes 48 hours to approve; from 8 days healthy babies need none, unless premature or with complications.
• Singapore Airlines: at least 7 days; 48 hours to 7 days only with medical clearance, booked through the airline.

On international routes the practical limit is usually the passport, not the airline: getting a baby's passport takes time, so babies flying to Bali from abroad are typically several weeks old.

How much is an infant ticket?

• Citilink: 10% of the adult basic fare, per one-way flight.
• Batik Air: 10% on domestic routes.
• Qantas: 10% of the adult fare on international routes (lap infant).
• Jetstar: fixed fee of AUD45 domestic and AUD75 international per infant per flight.
• AirAsia: fixed fee per flight that varies by route; we could not find the rupiah amount for Indonesia AirAsia, so check during booking.
• Garuda, Lion Air, Singapore Airlines: the infant percentage was not stated on the pages we checked; the price appears in the booking flow.

Lap infants generally get no baggage allowance of their own (Lion Air and AirAsia say so). Strollers usually travel free. All the airlines above allow one infant per adult, so twins need two adults.

Bassinets: who gets one?

• Garuda Indonesia: up to 9 kg, free on selected aircraft, booked through the call centre.
• Qantas: babies under 11 kg and under 2 years who can lie flat; charged in international Economy.
• Singapore Airlines: up to 14 kg, 768 x 298 x 158 mm, in Premium Economy and Economy. Scoot has no bassinets.

Each aircraft has only a few bassinets, allocated in booking order, so request one when you buy the ticket rather than at check-in. Single-aisle jets on Indonesian domestic routes generally have none.

Documents for the baby

• Foreign babies flying to Bali: need their own passport and their own visa. Indonesia's official eVisa site says every traveller, infants included, needs an individual visitor visa even if listed in a parent's passport.
• Rp150,000 foreign tourist levy: the exemption list in Bali's regional regulation does not mention children or infants, so budget for the baby too.
• Indonesian babies on domestic flights: CNN Indonesia (February 2025) advises having the family card (Kartu Keluarga) or birth certificate number ready when booking. We found no official airline rule on this, so carry copies.

Breast milk, formula and baby food in the cabin

At Indonesian airports, baby food, drinks and milk are exempt from the 100 ml limit under civil aviation decree SKEP/43/III/2007, as reported by CNN Indonesia and Haibunda. We could not confirm the decree is still in force unchanged, so carry reasonable amounts for the journey and be ready to open them at screening. On flights into Australia, powdered formula is exempt, but official sources disagree on expressed breast milk; ask security staff before you queue.

Vaccines for babies

No vaccine is required to enter Bali. The CDC recommends an early MMR dose for babies aged 6-11 months travelling abroad, and Australia's Smartraveller notes periodic measles outbreaks in Indonesia, Bali included. Talk to your paediatrician at least two weeks before departure; other vaccines are covered in our article on vaccines before Bali. If the traveller is a pregnant mother, airline pregnancy limits are in our article on flying to Bali while pregnant.

A late-night arrival with a baby is easier when the first night isn't spent on the road to Ubud or Canggu; an AccessiaPass hotel voucher can cover a night near the airport, and the areas are compared in our guide to staying near Ngurah Rai Airport.
