Indian airlines generally accept a birth certificate, a passport, Aadhaar, or a school identity card as proof of a child’s age on domestic flights. Accepted document lists vary by airline, so check yours before you travel. Age matters because infants under two travel on a parent’s lap and older children pay a child fare, and staff can ask for proof at the counter.

Adults flying within India need a government photo ID. Children are the grey area, and the rules read differently on every airline’s website. Here is what usually works and what is worth carrying anyway.
What documents count as proof of a child’s age?
Airlines want a document that states a date of birth and connects it to the child travelling with you. A municipal birth certificate is the most widely recognised of these, and a passport is the strongest single document because it proves age and identity together. Most carriers list several alternatives, though the exact list is set by each airline.
| Document | What it proves | Worth knowing |
|---|---|---|
| Birth certificate | Date of birth | Widely accepted. Carry the original or a certified copy, not just a phone photo. |
| Passport | Age and identity, with a photo | The cleanest option if your child already has one, including for domestic travel. |
| Aadhaar | Date of birth and identity | UIDAI issues an Aadhaar for young children, often called Baal Aadhaar, without biometrics at that age. |
| School identity card | Identity, and a date of birth if printed | Commonly accepted for school-age children. Check that the card actually carries the date of birth. |
| Hospital or immunisation record | Date of birth for a newborn | Sometimes accepted when a birth certificate has not yet been issued. Confirm with the airline first. |
Because these lists are set airline by airline, the safe move is to open your airline’s travel information page for infants and children before you pack, and carry the strongest document you have.
Why does the airline care about your child’s exact age?
Because age decides how your child travels, not just what you pay. Airlines generally treat a passenger under two years as an infant who travels on an adult’s lap without a separate seat, and a passenger from two years up to around twelve as a child who occupies a seat. Cross that boundary and the booking changes entirely.
Age also drives several other things on the day:
- Seat allocation. A lap infant is not assigned a seat, and safety rules restrict which rows an infant can occupy, including emergency exit rows.
- Bassinet eligibility. Bulkhead bassinets are offered subject to availability and to weight and size limits set by the airline, and they usually need to be requested in advance.
- Fare band. Child pricing differs by airline. Some apply a discount, others price a child’s seat close to an adult seat, so compare rather than assume.
- Baggage. The allowance attached to an infant is typically different from a child’s or an adult’s allowance.
If an airline cannot confirm the age at the airport, it can reasonably ask you to travel on the fare that applies to the age it can verify. That is the practical reason to carry proof even when nobody asks for it.
Does a child need their own ID at airport security?
Entry to an Indian terminal is controlled against your ticket and a valid photo ID, and security screening follows aviation security requirements administered through BCAS at every airport. In everyday practice, a young child accompanied by a parent or guardian is rarely asked to produce a separate photo ID at the terminal gate, and the accompanying adult’s ID does the work.
The airline check-in counter is a different conversation. That is where proof of age is genuinely requested, especially for a lap infant or where the booking was made in a child fare band. Two documents in your bag, one for age and one that ties the child to you, cover both situations comfortably.
If your family uses DigiYatra, check the app’s current rules for minors before you rely on it for everyone in the group, and be ready to use the regular ID lane if a child cannot be enrolled.
What happens if your child turns two during the trip?
This one catches out a lot of families. Airlines generally calculate age on the date of each flight, not on the date you made the booking. A baby who is under two on the outbound flight and turns two before the return has to be booked as a child with a seat for the return leg, even though the same trip covers both.
Check the birthday against both travel dates before you pay. Adding a seat later is usually more expensive than booking it correctly at the start, and on a full flight it may not be possible at all. The same logic applies at the upper end, where a child crossing into the adult band mid-trip needs the adult fare for the later leg.
What should you carry to the airport with children?
Keep it simple and keep it accessible, not buried in checked baggage. A short, practical list:
- Original birth certificate or passport for each child, plus a digital copy on your phone as backup.
- Aadhaar or a school ID with a date of birth, as a second option.
- Your own government photo ID, matching the name on your ticket.
- Any medical documents for a very young infant if your airline has asked for them.
- For a child travelling with only one parent or with a guardian, a consent letter and any custody or guardianship paperwork you have. It is not always required domestically, but it removes doubt if a question comes up.
Some airlines ask families travelling with a lap infant to complete formalities at the airport counter rather than online, so give yourself extra time. Reaching the terminal earlier than usual with small children is the single easiest thing you can do to make the morning calm.
Common Questions
Is a birth certificate compulsory for an infant on a domestic flight?
Airlines generally require proof of age for a lap infant, and a birth certificate is the document most commonly named. Some accept alternatives such as a passport or Aadhaar. Check your airline’s infant travel page and carry the original, since a photo on a phone is not always accepted.
How young can a baby fly?
Each airline sets a minimum age for infants, usually counted in days from birth, and some ask for a doctor’s fitness certificate for very young babies or after a complicated delivery. The thresholds are not uniform, so confirm with your airline before booking.
Does my child need a photo ID of their own?
For domestic travel with a parent or guardian, a separate photo ID is not usually demanded at terminal entry, though what the airline needs is proof of age at check-in. For older children, a school ID with a photo and a date of birth handles both purposes neatly.
Can two infants travel with one adult?
Generally no. Airlines normally allow one lap infant per accompanying adult, because the safety equipment for a lap infant is provided on that basis. A second infant usually needs a second adult, or a purchased seat with an approved child restraint device where the airline permits one.
How do I request a bassinet?
Ask at the time of booking or call the airline soon afterwards. Bassinets attach to bulkhead positions, are limited in number, and are subject to the airline’s weight and size limits, so request early and reconfirm before departure. They are never guaranteed.
What if I cannot prove my child’s age at the airport?
Expect questions and possible cost. The airline may ask you to travel on the fare that matches the age it can verify, which can mean paying for a seat you had not booked, and in a difficult case travel can be refused. Carrying one clear document avoids the entire situation.

Accepted documents, age bands and family travel rules change and differ by airline. Verify current specifics with the airline, DGCA, or the airport before you travel.
