What is the Delta Airlines Infant Policy?

The Delta Airlines Infant Policy is the set of rules designed for children under two years old who are not yet required to occupy their own paid seat. In simple terms, Delta recognizes that flying with a baby is different from flying with adults or older children. This policy allows infants to travel as “lap children” (sitting on an adult’s lap) for a drastically reduced fare—often just 10% of the adult fare plus taxes on international flights, or completely free on domestic U.S. flights when you select the “infant in arms” option at booking.

However, this policy goes beyond just pricing. It includes critical safety rules: only one lap child per adult passenger, no lap children in exit rows or bulkhead seats with airbag seatbelts, and specific age verification requirements. Delta also permits a ticketed seat for infants if parents prefer to use an FAA-approved car seat. The policy covers international nuances like passport requirements (yes, infants need passports for international travel), visa rules, and immunization documentation for select destinations. Understanding this policy is the difference between a smooth boarding process and being turned away at the gate.

 How Does the Delta Airlines Infant Policy Work?

Here is your step-by-step guide to navigating the Delta Airlines Infant Policy from booking to boarding:

• Step 1: Choose Your Travel Type & Add Infant at Booking

  • Start your flight search on Delta.com or the Fly Delta app. Add your own details, then look for the “Infant in Arms” or “Lap Child” option before searching.

  • Domestic: Select “infant under 2” – the fare will likely show as $0 plus taxes/fees.

  • International: The fare is typically 10% of the adult fare. You will still pay taxes.

  • Pro tip: Even if the infant is free, you must add them to the reservation to get a boarding document.

• Step 2: Decide on a Seat vs. Lap

  • Lap child: You hold the baby. No extra seat purchased. Best for short, direct flights.

  • Purchased seat for infant: You pay full child fare. You can bring an FAA-approved car seat (must have a hard shell and label stating “approved for aircraft”). This is safest for takeoff, landing, and turbulence.

• Step 3: Gather All Required Documents

  • Domestic: Birth certificate or hospital record (Delta may ask to verify age, though they rarely do for U.S. flights).

  • International: Valid passport for the infant (required even for newborns). Some destinations (e.g., South Africa, Brazil) require a visa. Check the U.S. State Department or Delta’s international travel page.

• Step 4: Check Baggage & Gear Limits

  • Stroller & Car Seat: Checked for free at the gate or ticket counter. No limit on one stroller + one car seat per infant.

  • Checked bag: International lap children often get one free checked bag (max 50 lbs). Domestic lap children generally do not get a free checked bag unless you have Delta Medallion status.

• Step 5: Arrive Early & Board with Early Access

  • Delta offers family boarding between Sky Priority and Main Cabin 1. Listen for “families with small children” or ask a gate agent. This gives you time to install car seats or get settled without rush.

 Important Rules, Fees, or Policy Details

When planning your trip, keep these concrete numbers and rules from the Delta Airlines Infant Policy handy:

• Change & Cancellation Fees for Infant Tickets

  • If you booked a refundable main cabin ticket for yourself, the infant’s lap fare is also refundable.

  • For non-refundable adult tickets, the infant’s $0 domestic fare can be cancelled without penalty. For international lap fares (10% of adult), that 10% is usually non-refundable unless you cancel within 24 hours of booking.

  • Grace period: Delta allows free cancellation for any ticket (including infant international tickets) within 24 hours of booking as long as the flight is at least 7 days away.

• Baggage Limits for Infants (Lap Child)

  • Stroller: One standard or umbrella stroller – free gate check.

  • Car seat: One FAA-approved car seat – free check (either at counter or gate).

  • Diaper bag: One carry-on diaper bag per infant – free and does not count toward your personal item limit.

  • Checked baggage: For Domestic – none unless you pay. For International – usually one piece up to 50 lbs (22.6 kg) and 62 linear inches.

• Age & Seat Restrictions

  • Infant must be under 2 years old on the date of departure.

  • If the infant turns 2 during a trip, you must purchase a child seat for the return flight.

  • Lap infants cannot sit in: Exit rows, bulkhead seats with airbag seatbelts, or rows designated as “no infant” due to oxygen mask configuration.

  • Only one lap infant per adult. An adult with two infants under 2 must purchase a seat for one infant.

• Refund Timelines for Infant Tickets

  • If you paid an international infant fare and qualify for a refund, Delta processes refunds in 7-10 business days to credit cards. If you paid with miles or a voucher, allow up to 14 days.

Common Problems and Solutions (Real Parent Stories)

Even with a clear policy, things go wrong. Here is how to fix the most frequent issues with the Delta Airlines Infant Policy:

• Problem: “The website won’t let me add my infant online after booking.”

  • Why it happens: Many third-party sites (Expedia, Priceline) or basic economy fares block infant additions post-booking.

  • Solution: Call Delta Reservations at 1-800-221-1212. Have your confirmation number ready. Ask an agent to “attach an infant in arms to the existing PNR.” Do this at least 48 hours before departure.

• Problem: The gate agent says my car seat isn’t allowed onboard.

  • Why it happens: Some European or older car seats lack the required “This restraint is certified for use in motor vehicles and aircraft” label (FAA sticker).

  • Solution: Before you travel, check the back or side of the seat. Only FAA-approved seats are allowed. If in doubt, gate-check it for free and hold the baby as a lap infant.

• Problem: My infant’s refund is delayed for an international trip we cancelled.

  • Why it happens: International infant fares (10% of adult) require manual processing.

  • Solution: Wait 14 business days, then use Delta’s “Request a Refund” form on their website. Select “Infant Fare” under ticket type. Attach proof of cancellation. Follow up via Twitter/X @Delta – their social media team is surprisingly effective for refund follow-ups.

• Problem: I was charged a change fee for my lap infant’s ticket after rescheduling my flight.

  • Why it happens: Sometimes Delta’s systems incorrectly flag a $0 domestic infant ticket as needing repricing.

  • Solution: Politely ask the agent to “waive the infant fare difference since the child is under 2 and remains a lap infant.” Most agents will fix it in seconds.

 Tips for Faster Help with Delta Airlines Infant Policy

Avoid hold times and airport stress with these practical, parent-tested strategies:

• Keep Your Booking Reference & Infant’s DOB Ready: Before you call or chat, have your 6-character confirmation code and your baby’s exact date of birth (MM/DD/YYYY) written down. This cuts call time by half.

• Use the Fly Delta App’s “Message Us” Feature: Instead of calling, go to the app → More → Contact Us → Message. Response times are often under 5 minutes for infant policy questions.

• Contact Support Early – Avoid 11 AM – 3 PM EST: The busiest call times are weekday mid-days. Call early at 7 AM or after 8 PM. Sunday evenings are surprisingly quiet for domestic support.

• Use Online “Manage Booking” First: 90% of infant policy needs (adding a lap baby, checking baggage allowance, printing infant boarding passes) can be done at delta.com → My Trips. Only call if you see an error.

• Visit a Delta Ticket Counter Day Before: If you live near an airport, go to the ticket counter the day before departure. Airport agents have more power than phone agents to override infant seat assignment issues.

• Ask for a “Gate Check Tag” for Stroller at Check-In: Do not wait until boarding. Get the pink or orange gate check tag when you print your luggage tags. This saves 15 minutes of scrambling at the gate.

 Frequently Asked Questions

Q1. Can infant tickets be changed online?
Yes, but only within certain limits. If you have a domestic lap infant ($0 fare), you can change your own ticket online and the infant will move with you automatically. For international lap infant tickets (that you paid 10% for), you must call Delta to change the infant’s booking – you cannot do it online.

Q2. How long do refunds take under the Delta Airlines Infant Policy?
For an international infant fare that you cancel, allow 7-10 business days for credit cards and up to 14 days for miles or vouchers. If you booked a $0 domestic lap infant, there is nothing to refund. For a purchased seat for an infant (full child fare), standard refund times apply: 7 days for credit cards.

Q3. What is the baggage allowance for an infant on Delta?
You get one free stroller, one free car seat (gate-check or counter-check), and one free diaper bag that fits under the seat. Domestic lap infants do not get a free checked suitcase. International lap infants get one free checked bag up to 50 lbs.

Q4. Is 24-hour cancellation available for infant tickets?
Yes. For any ticket (including an international infant fare) booked directly with Delta at least 7 days before departure, you have 24 hours from the time of booking to cancel for a full refund – no fees, no questions asked. This applies even if you bought a seat for the infant.

Q5. Can my 22-month-old sit in a car seat on the plane?
Absolutely. Delta encourages it for safety. You must purchase a separate seat for the infant (child fare). The car seat must have a hard shell and an FAA-approved sticker. It can only be placed in a window seat so it does not block the aisle.

Q6. Do I need a birth certificate for my infant to fly Delta domestically?
Delta does not require a birth certificate for domestic flights for infants under 2, but they can ask for proof of age. If your baby looks older than 2, bring a copy of their birth certificate or passport to avoid being forced to buy a full child fare at the gate.

 Final Words

Flying with a baby is rarely perfect, but understanding the Delta Airlines Infant Policy in advance removes most of the stress. For quick travel assistance, always check the latest policy on Delta’s official “Traveling with Children” page before booking, as rules for international health forms or car seat standards can change. Pack extra wipes, arrive early enough for family boarding, and remember that most Delta agents genuinely want to help parents succeed. Book with confidence, keep your infant’s documents handy, and enjoy your journey—you’ve got this. Safe travels from your family to the skies.
