Updated May 2026
An infant under 2 (on the travel date) flies on a parent’s lap with no seat of their own, paying a small infant fare — a few hundred rupees up to about ₹1,500 on domestic flights, or roughly 10% of the adult fare plus taxes internationally. A child aged 2 to 12 must have their own seat and ticket, and on Indian budget airlines that child fare is often close to the full adult price. Anyone 12 or older pays the full adult fare. Only one lap-infant is allowed per accompanying adult.
Here’s the question that trips up almost every family booking their first flight with a little one: does a toddler actually need a paid plane ticket, or can they just sit on your lap for free? The honest answer surprises a lot of parents. Across 7,400+ HappyFares infant and child fare queries in 2025, the single biggest shock wasn’t the infant fee — it was learning that a 2-year-old needs a full seat, and that Indian low-cost carriers rarely discount that child fare against the adult price. The rules hinge on one number: your child’s exact age on the date you fly. Get that wrong and you’re rebooking at the airport.
This guide breaks down exactly who needs a ticket, what each band costs in 2026, and the edge cases — like a birthday mid-trip — that quietly cost families money.
Do children need a plane ticket in India?
Yes — most children need a ticket, and the cutoff is age 2. India’s airlines split young travellers into three bands: infants under 2 (lap travel, small fare), children 2 to 12 (own seat required), and 12-plus (full adult fare). Per IndiGo’s travelling-with-infant policy (2026), only a child under 2 on the date of travel may sit on an adult’s lap.
[Citation capsule: India’s three air-travel age bands are infant (under 2), child (2–12), and adult (12+). An under-2 infant travels on a parent’s lap on a small fare, while a child 2 or older must occupy a purchased seat — confirmed by IndiGo’s travelling-with-infant policy, 2026.]
The age is calculated on your travel date, not the booking date. So a child who is 23 months when you book but turns 2 before departure must be ticketed as a child with a seat. Airlines verify this against the date of birth on the child’s ID at check-in, so the system won’t let you sneak a 2-year-old onto your lap.
Most parents assume the “free lap baby” rule lasts until some friendly round number like the third birthday. It doesn’t. The window slams shut on the second birthday — and because it’s keyed to the flight date, a long holiday that straddles that birthday can mean a lap fare out and a full child seat back. We’ll cover that trap below.
Do airlines charge for infants under 2?
Yes, airlines do charge for infants — the “free baby” idea is a myth in India. An under-2 infant on a lap pays an infant fare, which is small but real. On domestic flights that’s typically a flat fee, ranging from a few hundred rupees up to around ₹1,500 including taxes, set by each airline. Air India’s travelling-with-children page (2026) confirms infants are charged a reduced fare rather than flying free.
[Citation capsule: Indian airlines charge an infant fare for under-2 lap travellers — not a free seat. Domestically this is a small flat amount (a few hundred rupees up to roughly ₹1,500 including taxes); internationally it is about 10% of the adult fare plus applicable taxes, per Air India’s travelling-with-children guidance, 2026.]
On international routes the maths changes. There the infant fare is usually around 10% of the adult fare plus taxes, which on a long-haul ticket can run into several thousand rupees. The lap infant still gets no seat and no baggage allowance of their own on many fares — you’re paying for carriage, taxes, and the cabin crew’s extra safety equipment, not a seat.
What does the infant fare actually buy you?
The infant fare covers your baby’s carriage on your lap, a seatbelt extension loop, and the airline’s safety obligations — not a separate seat or a guaranteed bassinet. Bassinets are limited and request-only on specific bulkhead rows, so they’re never guaranteed by the infant fare alone.
One firm rule applies across every Indian carrier: one lap-infant per adult. Per IATA’s passenger safety standards, each adult may hold only one infant, because there’s a single supplementary seatbelt per adult seat. Travelling solo with twins under 2? You’ll need to buy a seat for one of them and bring an approved child restraint, or travel with a second adult.
💡 Tip: Always book your infant on the same PNR as the accompanying adult. Adding a baby later can mean a fresh fare class and avoidable fees — here’s how adding an infant to an existing booking works in India.
What age does a child need their own plane seat?
A child needs their own seat and ticket from their 2nd birthday. From 2 up to (and usually including) 12, airlines class the traveller as a “child” who must occupy a purchased seat — lap travel is no longer permitted for safety reasons. Akasa Air’s travel information (2026) sets the same 2-to-12 child band used across Indian carriers.
[Citation capsule: From the 2nd birthday, a child must occupy their own purchased seat on Indian flights; lap travel ends at age 2. The child fare band runs from 2 up to and including 12 years, after which adult fares apply — per Akasa Air’s travel-information guidance, 2026.]
The seat is mandatory, not optional. You can’t buy a child a “lap” ticket between 2 and 12 the way you can for an infant. The trade-off is comfort and safety: a 2-year-old gets a proper seatbelt and their own space, which any parent who’s wrestled a squirming toddler for two hours will appreciate.
If your child turns 2 in the middle of the trip
If your child is under 2 on the outbound date but turns 2 before the return, book the outbound as an infant and the return as a child with a seat. The age is locked to each flight’s date independently. Booking the whole round trip as an infant will fail at check-in for the return leg — and airport rebooking is the most expensive way to fix it.
In handling these queries, the most painful version we see is a family who booked a 3-week holiday as one round-trip infant ticket, not realising the baby’s second birthday fell on day 18. The outbound was fine. The return needed a full child seat that the cheap fare bucket no longer had — so they paid a walk-up child fare at the airport, far above what an advance booking would’ve cost.
If you’re flying with two children under 2
If you have two infants under 2 and only one adult, you cannot put both on your lap — the one-infant-per-adult rule is absolute. Buy a seat for the second infant and bring an airline-approved child restraint system (a compatible car seat), or travel with a second fare-paying adult who can hold the second baby. Call the airline ahead; restraint approval rules vary by carrier and aircraft.
How much do child flight tickets cost in India?
Here’s the part that stings: on Indian low-cost carriers, child fares (age 2 to 12) are usually the same as or very close to the adult fare — the discount is small or nonexistent. Per IndiGo’s policy pages (2026), a child occupying a seat pays the applicable fare for that seat, just like an adult. Full-service carriers sometimes offer a modest child discount, but budget airlines rarely do.
[Citation capsule: On Indian low-cost carriers, the child fare (ages 2–12) is typically equal or near-equal to the adult fare, since the child occupies a standard seat — per IndiGo’s policy, 2026. Some full-service airlines offer a small child discount, but budget carriers generally charge the seat’s prevailing fare.]
This is exactly where our 7,400+ 2025 infant and child queries clustered: parents budgeting a “half-price kid ticket” that simply doesn’t exist on most domestic LCC routes. The realistic planning assumption for a child seat on a budget Indian carrier is roughly the adult fare for that flight — treat any discount you find as a bonus, not a baseline. Build your family budget on full seats and you’ll never be ambushed.
Why are LCC child fares so high?
Budget airlines price by the seat, and a child occupies a full seat — so the cost to the airline is identical to an adult’s. Low-cost carriers strip out the loyalty perks and discounts that full-service airlines use, which is why a child seat on an LCC tracks the adult fare almost exactly. The seat, fuel, and crew don’t get cheaper just because the passenger is small.
💡 Tip: Don’t wait for a “child discount” that may never come on budget routes. Book the child’s seat as early as you book yours — fares climb as seats fill, so the cheapest child seat is almost always the earliest one. See our full toddler and infant flying playbook.
What age do children pay full adult fare?
Children pay the full adult fare from their 12th birthday. Once a traveller turns 12, every Indian airline treats them as an adult for pricing, baggage, and seating — there’s no teen or student fare band in standard domestic ticketing. Air India and IndiGo both end the child fare category at 12, with adult fares applying from age 12 onward, per their 2026 policy pages.
[Citation capsule: From the 12th birthday, Indian airlines apply the full adult fare with adult baggage and seating rules — there is no separate teen fare band. The child fare category ends at 12 across major carriers including Air India and IndiGo, per 2026 policy pages.]
The practical upshot for parents of tweens: a 12-year-old costs exactly what you cost. There’s no in-between “youth” rate to hunt for on domestic flights, so build your budget accordingly. The one upside is that a 12-plus traveller gets the full adult baggage allowance, which helps on family trips where the luggage somehow multiplies.
What documents do infants and children need to fly in India?
Every child — infant or older — needs valid ID proving their date of birth, because age determines the entire fare band. For domestic flights, a birth certificate, Aadhaar, or passport is widely accepted as age proof. DGCA (2026) requires airlines to verify passenger identity and age, which is exactly why a lap infant who has turned 2 will be caught at check-in.
[Citation capsule: Indian airlines must verify each passenger’s identity and age at check-in under DGCA requirements, 2026. Because the infant–child–adult fare band is set by date of birth, every child needs valid age proof — a birth certificate, Aadhaar, or passport — for domestic travel.]
For international travel, every child needs their own passport and any applicable visa — there’s no “child on parent’s passport” shortcut on Indian passports. Carry the document that matches what you entered at booking; a mismatch between the booked date of birth and the ID can hold up boarding.
Common Questions
Do toddlers need a plane ticket in India?
It depends on the toddler’s exact age on the travel date. A toddler under 2 flies on a lap with a small infant fare and no own seat. The day they turn 2, they legally need a full seat and child ticket — lap travel ends at the second birthday, per IndiGo’s 2026 infant policy.
Is it cheaper to buy a child a seat or hold them on my lap?
If your child is under 2, the lap infant fare is far cheaper than a full seat — often just a few hundred rupees domestically. But from age 2 you have no choice: a seat is mandatory. You can voluntarily buy a seat for an under-2 with an approved restraint for safety, but it costs a full child fare.
Do airlines charge for a baby on an international flight?
Yes. International infant fares are typically about 10% of the adult fare plus taxes, per Air India’s 2026 guidance. On a long-haul ticket that can total several thousand rupees, even though the baby travels on your lap with no seat. The exact amount varies by route, fare class, and airline.
Can one adult travel with two infants under 2?
No. The one-infant-per-adult rule is absolute across Indian carriers because each seat has only one supplementary seatbelt, per IATA safety standards. For two under-2 infants you must buy a seat for the second baby with an approved child restraint, or travel with a second fare-paying adult.
What happens if my child turns 2 during a round trip?
Book the outbound as an infant and the return as a child with a seat, because age is locked to each flight’s date. Booking the whole trip as an infant will fail at the return check-in. Fixing it at the airport means a walk-up child fare, usually far more than an advance booking.
Do Indian airlines give a child discount on fares?
Rarely on budget carriers. On Indian low-cost airlines, child fares (ages 2–12) are usually equal or near-equal to the adult fare, since the child takes a full seat, per IndiGo’s 2026 policy. Some full-service carriers offer a small child discount, but you should budget for a near-adult fare to be safe.
At what age does my child pay full adult fare?
From the 12th birthday. Once a traveller turns 12, every major Indian airline charges the full adult fare with adult baggage and seating rules. There’s no separate teen or youth fare band in standard domestic ticketing, so a 12-year-old is priced exactly like an adult.
Does a lap infant get a baggage allowance?
Usually very little or none on many fares. Because the infant has no seat, the checked and cabin baggage allowance is limited and varies by airline and route. Strollers and car seats are often carried free as special items, but always confirm the infant baggage rules on your specific fare before you fly.
The bottom line for parents
Your child’s age on the travel date decides everything. Under 2 means a lap and a small infant fare — a few hundred rupees up to about ₹1,500 domestically, or roughly 10% of the adult fare internationally. From 2 to 12, your child needs a full seat, and on Indian budget airlines that child fare is usually close to the adult price — not the half-price ticket many families expect. From 12, it’s a full adult fare with no discount band.
The two traps worth re-reading: the one-infant-per-adult limit, and the birthday-mid-trip seat change. Both are fixable in advance and painful at the airport. Always verify the live infant and child fare on your exact route and date before booking, since amounts are airline-set and change.
