Yes, a 3 year old needs their own flight ticket and seat in India. Only infants under 2 years can travel on an adult’s lap without a seat. From the age of 2, a child is treated as a child passenger, must have a ticket and a seat of their own, and should carry proof of age or an ID when travelling, because airlines can ask for it.

Parents often assume small children fly free for a few more years. On Indian airlines the free-seat window closes at the second birthday, so a three-year-old is a ticketed passenger.
At what age does a child need a flight ticket in India?
Indian airlines divide young passengers into an infant (under 2 years) and a child (from 2 years up to under 12). IndiGo’s pages state that infants under 2 cannot travel in their own seat and that no extra seat can be booked for an infant. Once a child reaches 2, a seat is required. Air India Express describes the same three bands: infant under 2, child 2 to 12, adult over 12.
So for a 3 year old, there is no lap-infant option. The child needs a ticket in their own name.
Is the age counted on the booking date or the travel date?
The travel date. IndiGo’s help content gives an example: an infant who is under 2 on the outward flight but turns 2 before the return flight is classified as a child needing a seat for the return. The same logic applies if your child turns 2 between booking and travel. Always count the age on each flight date, especially on round trips.
What does a lap infant cost, and is it ever an option for a 3 year old?
It is not an option for a 3 year old, but the figures are useful if you are travelling with a younger sibling. Under 2 years, an infant can sit on an adult’s lap, with one infant per adult. A fee applies:
- IndiGo: raised its domestic infant fee from 17 September 2026. Most news reports put it at Rs 3,000 per infant per sector, though figures differ between reports, so confirm the amount on IndiGo’s booking page.
- Akasa Air: also charges an infant fee on domestic flights; check the amount in Akasa’s booking flow.
A family with a 3 year old and a 1 year old would buy a seat for the older child and pay the infant fee for the younger one. Remember that one adult can carry only one lap infant. A second infant would need a seat of its own.
What ID does a young child need?
Domestic airlines in India generally ask for proof of age for infants and a valid ID for children, because the age band decides the fare. A birth certificate, a passport, or an Aadhaar card are the documents families commonly carry. Check the airline’s own list, since accepted documents can vary.
Carry the documents in your hand baggage rather than in a checked bag, because they may be asked for at the check-in counter, at the security point or at the boarding gate. If your child has no photo ID, a birth certificate or school ID is the sort of document families usually show, but the airline’s own list is the one that counts.
How should I book seats for a family with a 3 year old?
Book the child in the same booking as the adults so the names, ages and seats stay linked. Enter the child’s name exactly as it appears on their proof of age, and select the correct passenger type (child, not infant) when the booking form asks. If you choose seats yourself, try to place the child next to a parent. Some airlines charge for seat selection, and if you skip it, seats may be allotted automatically at check-in, so a family can end up apart. Checking in early on the web, which no Indian airline charges for, gives you the best chance of sitting together.
Finally, a small planning point: a 3 year old tires quickly, so a flight timed around nap time, with a snack and a favourite toy in your cabin bag, makes the journey easier for everyone.
Can a 3 year old travel without a parent?
Not alone. IndiGo’s pages say children aged 2 to 5 must be accompanied by a companion aged 18 or above. Unaccompanied minor services are for older children, on payment of an additional fee. If a grandparent or relative is taking your child, make sure the adult is named on the booking and carries the child’s proof of age. Confirm the exact rule with your airline.
Common Questions
Do children under 5 fly free in India?
No. Only infants under 2 travel without their own seat, and even then a fee applies. A child from 2 years needs a ticket.
Does a 3 year old pay the same fare as an adult?
The fare shown at booking applies to the child seat. Check the price breakdown on the airline’s booking page, because rules on child pricing can differ by airline and fare.
What if my child turns 2 just before our flight?
Then your child is no longer an infant for that flight and needs a seat. Age is counted on the date of travel.
Can I carry a 3 year old on my lap if the flight is short?
No. The lap rule is for infants under 2 and does not change with flight length.
Do I need a separate ticket if my child is sitting next to me?
Yes. A seat means a ticket, whether the child is in the next seat or the window seat.
Is there a fee for a child’s web check-in?
Checking in is free on Indian airlines, online or at the airport.
