Lap Infant vs Child Fares on Indian Airlines in 2026: Ages, Charges and What You Actually Pay

Flying with a baby or a young child raises an immediate question: do you pay a small lap-infant charge or a full child fare with a seat? Here's how IndiGo, Air India and Akasa define infant versus child in 2026, what each costs, the baggage rules for kids, and how to keep the bill down.
Quick answer
On Indian airlines, an 'infant' is under 2 years and travels on a parent's lap for a small charge, while a 'child' is 2–11 years and needs a paid seat (usually at or near the adult fare). As of June 2026, the lap-infant charge is modest (often a few hundred rupees plus taxes on domestic flights), whereas a child fare is effectively a full seat. The cut-off is the child's age on the travel date, not the booking date — a baby who turns 2 mid-trip needs a seat for the return. Confirm current infant charges on each airline's site; compare family fares in the FlightGPT chat.
How airlines define infant vs child
The age bands are standard across Indian carriers as of June 2026:
- Infant: under 2 years (0–23 months) on the date of travel. Travels on an adult's lap, no own seat, one infant per adult.
- Child: 2–11 years on the date of travel. Requires their own seat and a child fare.
- Adult fare applies from 12 years.
The age is assessed on each travel date. So if your baby is 23 months on the outbound and turns 24 months before the return, the return leg needs a child fare with a seat. Book accordingly to avoid an airport surprise.
What a lap infant actually costs
A lap infant doesn't get a seat, so the charge is small — covering taxes and a token infant fee rather than a full ticket. As of June 2026 this is typically a few hundred rupees plus applicable taxes on domestic Indian flights, and a percentage of the adult fare (commonly around 10%) plus taxes on international routes.
You must declare the infant at booking; you can't just turn up with a baby. The airline issues an infant ticket linked to the adult's PNR, and the baby sits on your lap with a special infant seatbelt the crew provides. For the full operational detail, see our flying-with-infants guide.
When you should buy a seat for an infant anyway
Even under 2, you can buy a separate seat for your infant and bring an approved car seat (CARES harness or an airline-approved child restraint). On a long international flight, many parents find the extra seat worth every rupee — a settled baby in a car seat beats a squirming lap-held one for hours.
The cost: buying a seat for an infant means paying a child fare (full seat) instead of the lap-infant charge. It's a big jump, so most domestic short-hop families stick with lap travel and reserve the paid-seat approach for long-haul. See our car seat and cot rules guide for what's allowed.
Baggage for infants and children
Allowances differ by age and airline. As of June 2026, broadly:
- Lap infants usually get a small checked allowance (often around 10 kg) on full-service/international, but little or none on the cheapest low-cost domestic fares — check your airline. You can almost always carry a stroller/pram free, gate-checked.
- Children with a seat get the same baggage allowance as an adult on the same fare.
Strollers, prams and car seats are typically carried free of charge in addition to your allowance — a genuinely useful perk for Indian parents. Confirm the stroller policy with your airline, as the gate-check process varies.
Bassinets, seating and the practical bits
On long-haul, request a bassinet (sky-cot) seat at booking — these attach to the bulkhead and are limited per flight, so book early. They're free but allocated first-come. For domestic short hops, bassinets aren't relevant. Note that lap infants can't sit in emergency-exit rows, and on most airlines only one infant is allowed per adult, so two adults are needed for two infants.
See our bassinet airline comparison for which carriers do baby-friendly best on routes from India.
How to keep the family bill down
Money-saving moves for Indian families: fly while your child is still under 2 to use the cheap lap-infant rate; book early for bassinet seats and to lock low child fares; compare full-service vs low-cost, because a full-service fare that includes infant baggage and a bassinet can beat a cheap low-cost fare once you add extras; and watch the age cut-off on the return leg.
Before booking, compare family pricing across airlines — infant charges, child fares and baggage all vary — in the FlightGPT chat, and check route pages like Delhi to Mumbai for typical fares.
Documents, IDs and international infant rules
Paperwork is where infant and child travel goes wrong. For domestic flights, carry proof of the child's age (birth certificate or passport) — airlines can ask, especially near the 2-year cut-off. For international travel, every child including a lap infant needs their own passport and, where applicable, their own visa — there's no 'add baby to parent's passport' option for Indian passports. See our infant and child visa guide.
Build in time for the infant's documents when planning an international trip, as passport issuance for minors takes weeks. Also confirm the airline's infant declaration is on your booking before you reach the airport — turning up with an undeclared baby causes problems. For the full first-trip-with-baby checklist, see our flying-with-infants guide, and compare family fares in the FlightGPT chat.
Key takeaways
To recap for Indian families: an infant is under 2 (lap travel, small charge), a child is 2–11 (own seat, child fare), and age is assessed on each travel date.
- Lap infant: a few hundred rupees plus taxes domestic; ~10% of adult fare plus taxes international. Declare at booking.
- Long-haul tip: consider buying a seat and using an approved car seat; request a free bassinet early.
- Strollers and car seats usually travel free in addition to your allowance.
- International: every child needs their own passport and visa — plan weeks ahead.
Watch the 2-year cut-off on the return leg, and compare full-service versus low-cost family pricing in the FlightGPT chat, since infant charges, child fares and baggage all vary by airline.
Frequently asked questions
What age is an infant vs a child on Indian airlines?
As of June 2026, an infant is under 2 years (travels on a lap for a small charge), and a child is 2–11 years (needs a paid seat). Adult fares apply from 12. Age is assessed on each travel date, not the booking date.
How much does a lap infant cost on a domestic Indian flight?
A lap infant typically costs a few hundred rupees plus taxes on domestic flights as of June 2026, since the baby has no seat. On international routes it's usually around 10% of the adult fare plus taxes. Confirm on the airline's site.
Do I need to buy a seat for my baby?
Not for an infant under 2 — they travel on your lap. You may optionally buy a seat (paying a child fare) and bring an approved car seat, which many parents prefer on long-haul flights. A child aged 2+ must have their own seat.
Can I carry a stroller free when flying with a baby?
Yes. Strollers, prams and car seats are typically carried free of charge in addition to your baggage allowance on Indian airlines, usually gate-checked. Confirm the gate-check process with your specific airline before travel.
What if my child turns 2 during the trip?
Age is assessed on each travel date, so if your child turns 2 between the outbound and return, the return leg requires a child fare with its own seat. Book the return as a child fare to avoid an airport problem.
