The minimum age for a newborn to fly in India differs by airline — IndiGo requires at least 7 days for domestic travel, while Air India will accept an infant as young as 48 hours old if accompanied by a paediatrician's fitness certificate. International flights have stricter guidance, and if the mother delivered by caesarean, there are additional clearances to arrange.
TL;DR — The Short Answer
The minimum age for a newborn to fly in India is 7 days on IndiGo (domestic), 48 hours on Air India (domestic, with a paediatrician's fitness certificate), and broadly 14 days for international travel on most carriers — though Air India Express and Akasa Air follow similar logic to their domestic rules. Every airline reserves the right to refuse boarding if the infant looks unwell or if documentation is incomplete. Get everything in writing before you book.
IndiGo's Newborn Rules — 7 Days Minimum Domestic
IndiGo's policy (as of 2026) states that infants must be at least 7 days old to travel on domestic routes. There's no waiver for this — a paediatrician's letter won't help you fly a 5-day-old on IndiGo. This minimum applies to both the infant-on-lap booking (where infants pay a nominal fare) and any separately-purchased infant seat.
At the airport, IndiGo's check-in staff can and do ask for the birth certificate to verify the infant's age. If you don't have the original, a hospital discharge summary with the date of birth is usually accepted. Don't assume the staff won't check — I've seen parents turned away at the counter for not having documentation.
For international flights, IndiGo aligns with broadly accepted industry guidance of around 14 days minimum, and will sometimes require a paediatrician's clearance letter in addition. Verify this directly with IndiGo's customer care for the specific route.
Air India's Policy — 48 Hours With a Paed Letter
Air India is notably more permissive: they accept infants as young as 48 hours old on domestic routes, provided you carry a paediatrician's certificate confirming the infant is fit to fly. This is the airline's formal stated policy, though individual ground staff can exercise discretion if the infant appears in distress.
The fit-to-fly letter should ideally be issued within 24–48 hours of the travel date, on the doctor's letterhead, stating the infant's name, date of birth, weight, and confirmation that the infant is medically cleared for air travel. Vague letters get questioned — be specific in what you ask the paediatrician to write.
For international travel on Air India, the minimum rises to around 14 days, consistent with IATA guidance. The same paediatrician's letter is required, and you should carry it even if nobody asks — airports sometimes do spot checks at immigration.
Air India Express and Akasa Air — What's the Rule?
Air India Express (the low-cost arm of Air India, now fully integrated under the Air India brand) typically follows Air India's policies for infant age minimums, so 48 hours domestic with medical clearance. That said, international routes from secondary Indian airports served by Air India Express may be subject to stricter rules by destination-country airlines or transit airports. Always call the Air India care line to confirm for your specific route.
Akasa Air, India's newest carrier, requires infants to be at least 7 days old for domestic travel — in line with IndiGo. Their policy page (check akasaair.com for current terms) is reasonably clear on this. SpiceJet, which operates a limited schedule as of 2026, also requires a minimum of 7 days for domestic infant travel.
The bottom line: if you're trying to fly within the first week of birth, Air India with a paediatrician's letter is currently your best — and arguably only — option on a mainstream Indian carrier.
The Caesarean Factor — Extra Documents Needed
If the mother delivered via C-section, there are two separate medical clearances to consider: one for the infant, and one for the mother herself.
Most airlines recommend (and some require) a fit-to-fly certificate for post-caesarean mothers, particularly within the first 6 weeks after delivery. Flying too soon after a C-section carries real medical risk — blood clots, wound complications, reduced mobility in an emergency. The DGCA doesn't mandate a specific restriction, but most airline medical teams advise waiting at least 4–6 weeks before flying after a caesarean. Air India's medical team explicitly says this on their health-on-board guidance pages.
For the infant, the standard age rules above apply regardless of delivery method. But practically speaking, if a C-section was complicated or the infant required NICU time, any airline's ground staff can and will ask for clearance beyond the standard minimum. Don't try to wing it — get the documentation and you'll have no trouble.
Documents to Carry at the Airport — A Practical Checklist
Airlines can be inconsistent in what they ask for, but carrying all of these means you're covered regardless:
- Birth certificate or hospital discharge summary with the infant's full name and date of birth
- Paediatrician's fit-to-fly letter (mandatory on Air India, strongly advisable on all carriers for infants under 3 weeks)
- Parent's photo ID (Aadhaar, passport) — the infant doesn't need their own ID for domestic travel, but the parent does
- For international travel: infant's passport (essential — newborns need their own passport for international flights)
- If mother had a C-section: obstetric fit-to-fly letter for the mother
A note on the infant's domestic travel: inside India, infants don't need a separate ID document — the hospital discharge summary with the child's name and DOB is sufficient. For international travel, the infant needs a full passport — start the process immediately after birth registration, as government offices now typically take 2–4 weeks for infant passports.
Bottom Line — and When to Just Wait
Flying with a newborn is legal, possible, and done by plenty of Indian families every week. But the first two weeks of a baby's life are medically significant — immune systems are immature, pressure changes affect tiny ear canals, and cabin air is dry. If you can wait until the 2-week or 4-week mark, most paediatricians will tell you it's measurably safer and easier. If you genuinely can't wait — say, a family emergency across the country — Air India's 48-hour minimum with a paed letter is your window.
Use FlightGPT to find flights, and call the airline's customer care to confirm current policy before booking — airline rules do update and the call centre representative will note the confirmation on your PNR.
Frequently asked questions
What is the minimum age for a newborn to fly IndiGo domestically in India?
IndiGo requires infants to be at least 7 days old for domestic travel. No exceptions or medical waivers are available — a paediatrician's letter won't override this minimum. Carry the birth certificate or hospital discharge summary as proof of age.
Can a 3-day-old baby fly on Air India?
Air India's stated minimum for domestic travel is 48 hours (2 days), provided you carry a paediatrician's fit-to-fly certificate. A 3-day-old would technically meet the minimum. However, individual ground staff can decline boarding if the infant appears unwell. Get the paed letter, arrive early, and carry the hospital discharge summary.
Do newborns need their own ticket or ID for domestic flights in India?
Newborns don't need a separate government-issued ID for domestic flights — the hospital discharge summary with date of birth is sufficient. They do need a ticket (booked as an infant-on-lap, typically at a nominal fare). For international travel, a full passport is mandatory even for a 7-day-old infant.
When can a mother fly after a C-section?
Most airlines and medical guidelines recommend waiting at least 4–6 weeks after a caesarean before flying. Air India's onboard health pages advise this explicitly. If you must fly earlier, carry a fit-to-fly letter from your obstetrician — some airlines make this mandatory, and all can request it.
What documents does a paediatrician's fit-to-fly letter need to include?
At minimum: the infant's full name, date of birth, weight, the specific flight date and route, confirmation that the infant is medically cleared for air travel, and the paediatrician's signature, stamp and registration number. Vague letters (just 'fit to travel') often get questioned at check-in. Issue it within 48 hours of the flight.
What is the minimum age for an international flight with an Indian airline for a newborn?
Most Indian carriers — Air India, IndiGo, Akasa Air — follow IATA's general guidance of 14 days minimum for international travel. Air India may require a paediatrician's certificate regardless of the infant's age for international routes. Check with your specific carrier and also the destination country's entry rules, which can impose their own restrictions.
