Travel Documents Required for Infant or Child Under 2

Travel Documents Required for Infant or Child Under 2

Infants under 2 need to be added to the booking even when they travel on an adult’s lap. The documents you need depend on whether the trip is within India or international, the airline, the child’s age, and whether both parents are travelling.


For domestic India flights, carry reliable age proof. For international travel, your child needs their own passport and may also need a visa, consent letter, health documents, or destination-specific paperwork.

Quick Answer: Documents for Infants and Children Under 2

For a domestic India flight, carry valid proof of your infant’s age. For an international flight, your child needs their own passport and may need a visa, entry permit, parental consent letter, or other destination-specific documents.

Trip Type Main Documents to Carry Why They Matter
Domestic flight in India Infant age proof and adult traveller’s valid ID Shows the child qualifies as an infant and is travelling with the booked adult
International flight Child’s passport, visa or entry permission, booking documents Required for immigration and entry into another country
One parent travelling alone Passport, birth certificate and possible consent letter Some countries or airlines may ask for proof of parental permission
Grandparent or other guardian travelling Child’s documents plus consent and relationship details Helps show the adult is authorised to travel with the child
Medical needs Prescription, doctor letter and medicine label Useful for medication, formula, devices or special assistance

Documents for Domestic Flights in India

For domestic travel, the airline may ask for proof that the child is under 2 years old on the date of travel. IndiGo lists a birth certificate, mother’s hospital discharge summary, vaccination certificate, or passport as accepted infant age proof.

Carry the adult traveller’s original government-issued ID as well. The name on the booking should match the adult’s identification document.

Useful domestic-flight documents

  • Original birth certificate.
  • Infant passport, if available.
  • Mother’s hospital discharge summary for a very young infant.
  • Vaccination certificate showing the child’s name and date of birth.
  • Adult parent or guardian’s original government-issued photo ID.
  • Flight booking or itinerary showing the infant added to the reservation.

Do not rely only on a photo of a birth certificate. Airlines may want to see an original document or another acceptable original age-proof document at check-in.

Documents for International Flights

International travel is different. Every infant, including a newborn travelling on a parent’s lap, needs their own travel documents. A child cannot travel internationally using only a parent’s passport or ticket.

Document Usually Needed? Why
Child’s passport Yes Required for international travel and immigration
Visa or electronic travel authorisation Depends on destination Required where the destination country requires it
Return or onward ticket May be requested Some destinations require proof of onward travel
Birth certificate Useful to carry Can help show parentage and age
Consent letter May be needed Useful when one parent or another guardian travels with the child
Health or vaccination records Depends on route and destination Some countries may have health-entry requirements

Air India advises international passengers to carry a valid passport, visa, entry permit, and any required health certificates. Check the immigration requirements for the country you are entering, not only the airline’s policy.

Accepted Proof of Age for Infants

Airlines need proof of age because infant fares, lap-infant rules, bassinets, and seating restrictions are based on the child’s age on the travel date.

Document Can It Help Prove Age? Best Use
Birth certificate Yes Best general document for domestic infant travel
Passport Yes Required for international trips and useful for domestic travel
Mother’s hospital discharge summary May be accepted Useful for very young infants
Vaccination certificate May be accepted Useful backup age proof for domestic travel
Digital photo of a document Not always accepted Backup only, not your primary proof

Does an Infant Need a Ticket and Boarding Pass?

Yes. Even when an infant travels on an adult’s lap and does not have a separate seat, the child must be added to the booking. The airline needs to know every person on board for safety, seating, and passenger records.

An infant booking may involve an infant fare, taxes, or route-specific charges. Check your booking confirmation before travel to make sure the infant’s name and date of birth are correct.

Check before leaving home: your boarding documents should show that the infant is attached to the adult traveller’s booking. Do not assume the airline will add the child automatically at the airport.

Does an Infant Need a Passport and Visa?

Yes, an infant needs their own passport for international travel. Indian minor passports are generally valid for five years or until the child turns 18, whichever comes first.

Visa requirements are set by the destination country. Some destinations may require a visa, electronic travel authorisation, transit visa, vaccination certificate, or additional entry form for an infant just as they do for adults.

Before booking an international trip

  • Apply for the child’s passport early.
  • Check visa rules for the destination and any transit country.
  • Make sure the child’s name matches the passport exactly on the airline booking.
  • Check passport-validity requirements for the destination.
  • Confirm whether the child needs a separate visa application.
  • Carry printed copies of passport, visa, travel insurance and booking details.

Travelling With One Parent or Another Guardian

A child can travel with one parent, but certain countries, airlines, and immigration officers may request evidence that the other parent or legal guardian has agreed to the trip. This is especially important when surnames differ or the adult is not the child’s parent.

A consent letter is not automatically required for every flight from India, but it is a sensible document for an international trip where one parent is absent. Check the entry rules of the destination country before travel.

A useful consent letter can include

  • Child’s full name, date of birth and passport number.
  • Travelling parent or guardian’s full name and passport details.
  • Non-travelling parent or guardian’s full name and contact details.
  • Travel dates, flight details and destination.
  • Permission for the named adult to travel with the child.
  • Signature of the non-travelling parent or legal guardian.
  • Supporting identification copies where appropriate.

Guardian travel tip: When a grandparent, aunt, uncle, family friend, or another guardian is travelling with the child, carry a signed authorisation letter, the child’s birth certificate, and copies of the parents’ identification and contact details.

Can One Adult Travel With Two Infants?

Usually, one adult can travel with only one lap infant because each infant needs individual support during an emergency. IndiGo states that only one infant per adult is permitted.

If you are travelling with two children under 2, you may need another adult traveller or a separate seat for one child. Confirm this before booking because airline seating and safety rules can differ by aircraft and route.

Infant Check-In and Airport Tips

Allow extra time at the airport when travelling with a baby. Check-in staff may need to verify age proof, issue the infant boarding document, review a stroller or car-seat request, and confirm seating arrangements.

  1. Bring original age-proof documents in your cabin bag.
  2. Confirm the infant is listed on the booking before arriving at the airport.
  3. Arrive early enough for document checks and stroller drop-off.
  4. Keep passport and visa documents together for international travel.
  5. Carry formula, baby food, diapers, wipes, and medicines in an easy-to-reach bag.
  6. Ask the airline about bassinets, stroller handling, and infant baggage allowance before travel.
  7. Keep a digital backup of important documents, but do not rely on it as the only proof.

Health, Medicine and Medical Documents

Most healthy infants do not need a medical certificate for routine travel, but airlines can have minimum-age rules and may ask for medical clearance in certain circumstances, such as premature birth, recent illness, oxygen needs, or other medical conditions.

Carry a doctor letter or prescription when travelling with medication, special formula, medical devices, injectable medicine, or a baby with a health condition that may need explanation at security or during the flight.

Check before booking very young infants: airlines set their own minimum-age policies. Do not assume every airline accepts a newborn at the same age.

Infant Travel Document Checklist

Domestic India flight checklist

  • Infant booking confirmation.
  • Original birth certificate, passport, vaccination certificate, or hospital discharge summary.
  • Parent or guardian’s valid original ID.
  • Medical documents if the infant has special travel needs.
  • Stroller or car-seat booking information where relevant.

International flight checklist

  • Infant’s valid passport.
  • Visa, entry permit, or electronic travel authorisation if required.
  • Infant booking and boarding documents.
  • Birth certificate.
  • Consent letter where one parent or another guardian is travelling.
  • Travel insurance details.
  • Health certificates, vaccination proof, or medical documents if required.
  • Return or onward ticket where the destination requires it.

Mistakes to Avoid

  • Turning up with an infant who was not added to the booking.
  • Leaving age proof at home for a domestic flight.
  • Using only a phone photo of a birth certificate.
  • Assuming an infant can travel internationally on a parent’s passport.
  • Booking the child’s name differently from the passport.
  • Ignoring visa or transit-country entry requirements for the infant.
  • Travelling with one parent or a guardian without checking consent-letter requirements.
  • Assuming one adult can carry two lap infants.
  • Arriving late and not allowing time for document checks.
  • Leaving medical documents in checked baggage instead of the cabin bag.

Bottom Line

For a domestic India flight, take original proof of your infant’s age and your own valid ID. For an international flight, the child needs their own passport and may also need a visa, entry approval, consent letter, or health documents.

Put every original document in your cabin bag, confirm the infant is added to the reservation before travel, and check the exact airline and destination-country rules before you leave for the airport.

Frequently Asked Questions

What documents does an infant need for a domestic flight in India?

Carry the infant’s age proof, such as a birth certificate, passport, vaccination certificate, or mother’s hospital discharge summary. Also carry the accompanying parent or guardian’s original valid ID.

Does an infant need a boarding pass?

Yes. Even when an infant travels on an adult’s lap without a separate seat, the child must be added to the booking and included in the airline’s boarding records.

Does an infant need a passport for an international flight?

Yes. Every infant needs their own valid passport for international travel.

Does a baby need a visa?

Usually yes when the destination country requires visas for travellers. Check the visa and entry rules for the child’s nationality, destination, and any transit country.
