Travelling with a car seat or CARES harness on Indian flights — what IndiGo and Air India actually allow (2026)

Here is the frustrating truth: Indian carriers do not have a uniformly clear published policy on car seats and CARES harnesses the way US carriers do. In practice, most airlines will permit a government-approved child restraint device on a purchased seat — but you need to know the aircraft type, the approval label requirement, and exactly which IndiGo or Air India cabin configuration allows it. Here is what is actually known.
TL;DR — the short answer
You can use a Child Restraint System (CRS) — a car seat — on an Indian flight if the child has a paid seat, the device has the required FAA TSO-C100b label (or equivalent DGCA/EASA approval marking), and the aircraft type and cabin configuration permit it. The CARES harness (a belt-extension-style restraint for children approximately 22–44 lbs / 10–20 kg) is similarly permitted on a purchased seat. Neither device is permitted if the child is travelling as a lap infant (free of charge) — the seat must be bought and paid for. No Indian carrier currently has a policy that proactively publicises this the way Southwest or United do in the US — you have to ask at booking and confirm at check-in.
Lap infant vs. paid seat — understanding the baseline
Before getting into CRS specifics, it helps to understand the two ways an infant or toddler travels on Indian flights:
- Lap infant (free or nominal fee): Children under 2 years on IndiGo and Air India can travel on a parent's lap. IndiGo charges a nominal infant fee (typically a few hundred rupees plus airport taxes per sector — check the booking flow for the current amount). The child has no seat of their own. In this arrangement, no car seat or CARES harness can be used — there is no seat to attach it to.
- Purchased seat for the child: A child of any age can have a full-price seat purchased for them. Infants under 2 travelling in a CRS must have a paid seat. This is not cheap — you pay the child's full fare — but it is the only way to use a car seat or harness legally on the aircraft.
The economics are real: for a family of two adults with an 18-month-old, buying a third seat on a peak-season IndiGo Delhi–Mumbai route could add ₹3,000–₹8,000 to the cost depending on the fare class and date. But if you have a car seat you want to use for safety reasons, there is no workaround — the seat must be bought.
What approval label does the car seat need?
This is where it gets very specific. Airline regulations on child restraint devices (globally and in India) require that the CRS carry one of these markings:
- FAA TSO-C100b — the US Federal Aviation Administration's certification for child restraint systems used on aircraft. The label reads: 'This child restraint system conforms to all applicable Federal motor vehicle safety standards' AND 'This restraint is certified for use in motor vehicles and aircraft.'
- EASA (European) equivalent approval — the European label reads: 'Approved for use in aircraft' or similar EC/EASA marking.
- A label stating it is approved for aircraft use in the country of manufacture.
The critical point: not all car seats sold in India carry the aircraft-use label. Many popular Indian market car seats (from brands like Luvlap, R for Rabbit, Safe-O-Kid) are certified to Indian road safety standards (AIS 129 or the older IS/AIS norms) but are not FAA TSO-certified for aircraft use. If the seat does not have the aircraft-use certification printed on it, an airline is within its rights to refuse to let you use it on the flight — and some ground staff will check.
Brands that commonly carry the FAA/aircraft-use label and are used by India-based travellers: Maxi-Cosi (certain models), Graco (certain models imported via grey market or purchased abroad), Chicco. Always check the label on your specific model — not all models from a brand are certified.
What is the CARES harness and is it allowed on Indian flights?
The CARES (Child Aviation Restraint System) harness is an FAA-approved device that uses the aircraft seatbelt as a base and adds shoulder straps and a crotch strap to secure a child aged approximately 3–5 (or in the 22–44 lbs weight range). It is compact, folds into a small bag, and is far easier to carry through airports than a full car seat.
The CARES harness is FAA-approved and cleared for use on aircraft and in theory should be permitted on Indian flights on a purchased seat. The practical situation: IndiGo's published policy does not explicitly mention the CARES harness (as of mid-2026, this was not clearly listed in IndiGo's passenger services documentation). Air India's international operations and codeshares reference DGCA and IATA guidelines which broadly permit IATA-approved CRS devices including harness-type devices.
The safe approach: contact IndiGo or Air India reservations by phone before travel, describe the specific device (CARES harness, manufacturer, model number, FAA approval label), and get written or emailed confirmation that it will be permitted. Print that confirmation and carry it to the airport. This is exactly the kind of policy gap that leaves families in trouble at the gate when a ground agent has never seen the device before.
Aircraft types and seat configurations — what fits and what does not
Even an FAA-approved CRS cannot be used in every seat on every aircraft. The constraints:
- Emergency exit row seats: No CRS of any kind is permitted here — exit row passengers must be able to assist in an evacuation, and this excludes children in restraint devices.
- Seats with airbags (Air India's wide-body international aircraft): Some Air India 787 Dreamliner and 777 seats in business and premium economy have airbag seatbelts. A CRS cannot be used with an airbag belt — ask Air India reservations to assign a seat that does not have the airbag belt if you are using a CRS on a wide-body aircraft.
- IndiGo's Airbus A320/A321 family (domestic): Standard economy rows without airbag belts. A forward-facing CRS in a window seat in rows away from the exit (typically rows 11–25 on an A320, though it varies by aircraft) is generally feasible. The child's seat must face forward (rear-facing car seats have specific row and direction requirements and may not fit due to the pitch of IndiGo's seats, which is typically in the range of 28–30 inches — snug for a rear-facing shell seat).
- Rear-facing infant seats: These require the airline to confirm that the seat pitch and the row ahead allow space. Many IndiGo rows are too close-pitched for a rear-facing infant bucket seat — this is a real physical constraint, not a policy one. Some parents find that bulkhead rows (where there is no seat in front) or overwing rows work for rear-facing seats; call to check before assuming.
How to actually do this without a surprise at the gate
The step-by-step approach that avoids the most common failure point (an uninformed gate agent refusing the device):
- Buy a paid seat for the child. No car seat on a lap infant — this is non-negotiable.
- Verify your device has the FAA TSO-C100b or equivalent aircraft-approved label. Check physically on the device — not on the manufacturer's website.
- Call IndiGo's contact centre or Air India reservations and specifically ask about the device. Give them the brand, model and approval label. Note the agent's name and date of the call.
- Request the right seat type at booking — a window seat in a non-exit, non-bulkhead-airbag row. Ask the reservations agent to note this on your booking.
- Arrive early at the airport and mention the car seat to check-in staff before they try to check it as hold luggage (car seats can travel in the hold free of charge on most Indian airlines as an extra item — confirm this with your airline at booking).
- At the gate, show the device label and your written airline confirmation proactively to the gate agent before boarding. Gate agents who have not seen a CARES harness before will be reassured by documentation rather than a verbal claim.
Search for family-friendly fares on FlightGPT and check airline timing options that give you more ground time — the earlier departure slots on domestic routes tend to have calmer airports and more helpful ground staff than the last-evening rushes. Also useful: baby food at Indian airport security and unaccompanied minor rules on IndiGo and Air India.
Frequently asked questions
Can I use my Indian-purchased car seat on an IndiGo flight?
Only if the seat carries the FAA TSO-C100b label or equivalent aircraft-use certification printed directly on it. Many popular car seats sold in India are certified to Indian road standards but not FAA-certified for aircraft use. Check the label physically on your device before assuming it qualifies.
Does the child need a paid seat to use a car seat on an IndiGo or Air India flight?
Yes, absolutely. A car seat or CARES harness requires a purchased seat — a child travelling as a lap infant (no seat allocated) cannot use any restraint device. You will need to buy the child's seat at the applicable fare for their age and route.
Is the CARES harness allowed on IndiGo flights?
The CARES harness is FAA-approved for use on aircraft, but IndiGo's published documentation does not explicitly list it as of mid-2026. Call IndiGo reservations before travel, describe the device specifically, and get written confirmation. Carry that confirmation to the airport to avoid a gate-level dispute.
Can I use a rear-facing car seat on an IndiGo A320 domestic flight?
It depends on the specific row and seat pitch. IndiGo's A320 economy cabin has a seat pitch typically in the 28–30 inch range, which is tight for a rear-facing shell car seat — many models physically will not fit with the tray table of the seat in front. A bulkhead row (no seat in front) may work for some models. Confirm with IndiGo reservations before booking.
Does a car seat travel free of charge in the hold on Indian airlines?
Most Indian airlines — IndiGo and Air India — allow a car seat to be checked as additional baggage free of charge, similar to prams and pushchairs. Confirm this with your specific airline at booking, as policies can be updated. The car seat must be in a protective bag or box for hold travel.
Can I use a car seat on Air India's international wide-body flights?
Yes, with caveats: on Air India's 787 Dreamliner and 777 international flights, some seats have airbag seatbelts (common in premium economy and some economy rows), and a CRS cannot be used with an airbag belt. Request a seat assignment in a standard-belt row when booking, and mention you are bringing a CRS. Air India's international policy references IATA guidelines which permit IATA-approved CRS devices.
