Delta Airlines Infant Policy 2026 | Rules, Fees & Guide!

Keeping your baby dude with you may be confusing, particularly when you find out that tickets, seating, bags, car seats, and paperwork require some tidying up. The existing Delta Airlines infant policy allows babies under 2 years old to travel as an Infant-in-Arms on qualifying domestic flights, and provides a seat for parents, who are allowed to use an approved child restraint. Most countries have infant fares and require more paperwork for international travel.

How old can a baby be to fly on Delta Airlines?

Delta considers a baby less than 2 years of age as an infant; this is the age it considers as a "baby". If you have a baby under 7 days old, they have another restriction and may require a letter of authorization from their doctor to fly.

Here are some of the important rules for each age level:

  • Under 7 days: Medical clearance may be required.
  • Under 2 years: The child can be transported as an Infant-in- Arms or in an Infant in a separate purchased seat.
  • Age 2 or older: Children must have their own ticket, their own seat.
  • Turns 2 during the trip: The parent/guardian should book the appropriate seat on the cruise/ship for the trip.

Do infants fly free on Delta Airlines?

Yes, but this will be determined by the travel schedule and seat configuration. Infants age 2 years or under may travel as lap infants on flights within the United States for free, but must be added to the reservation. Infant-in-Arms travel is free, within the U.S. and Canada. Travel abroad with a baby is typically on an infant rate, typically 10% discount off of the adult price, and often with charges and taxes as well.

Important points are:

  • If the child is in a delta lap seat (whether on an aircraft or in a freestanding stroller) there is no separate aircraft seat provided for them.
  • The parent must remain with the baby.
  • Fares from around the world may also be different, depending on where you go.
  • Every individual paying for his/her own seat will pay the applicable fare.
  • Parents are encouraged to bring the infant on the booking and not to the airport with the baby.

You can, for instance, book a flight from Chicago to Los Angeles with your 10-month-old bug as Infant-in-Arms without an additional ticket for a baby.

How do you add an infant to a Delta flight reservation?

The booking process supports the online inclusion of parents and they can add an Infant-in-Arms when the booking process enables such inclusion. The instructions Delta are giving travellers are: Click the Open Trip button, go to the Special Service Requests section, choose the Infant-in-Arms option, input the required details and confirm the request.

A simple process is:

  • Open your Trips on Delta.
  • Choose the appropriate reservation.
  • Find Special Service Requests.
  • Unlock the Infant in Arms iOS Mode.
  • Fill in the baby's necessary details.
  • Confirm the request.

Please review the new reservation before traveling.

If it's not available online, call Delta Reservations.

What documents does a baby need to fly on Delta?

The documentation varies with the path, the baby's age and countries. Newborn under 7 days may need a physician's choice letter from Delta, as well.

Parents should carry:

  • Baby's passport for international travel.
  • Hold visas or entry papers, where necessary,
  • Prevalence information (if applicable) including birth certificate.
  • If required, a newborn will have physician approval documentation.
  • Picture ID of accompanying adult.
  • Custody/consent documents required for international travel.

Carry vital documents in a hand-carried bag and not in a checked bag.

Can two infants travel with one adult on Delta?

No. Delta adheres to the safety code that only one baby can be strapped in the lap of one adult at a time. A seat must be purchased for an extra infant when 2 are traveling with one adult.

If a parent is traveling with twins one of the babies could be an Infant-in-Arms, and the other baby PTA requires a ticketed seat. They should use the child restraint seat as per Delta & FAA requirements.

Should you buy a separate seat for an infant on Delta?

As long as the parents qualify for a delta lap infant car seat, they do not need to buy their own seat for the lap infant on their qualifying domestic travel. But with the money spent on a delta seat, the baby has a designated planter and the family can utilize a given working child safety seat.

Booking a separate seat will be done:

  • In case of a long flight.
  • A car seat that is familiar to the baby is helpful for his sleep.
  • Parents want more time to themselves.
  • The family wishes to use an approved restraint system.
  • The infant is riding on a trail that requires a separate ticket.

An infant on board accompanied by their own seat – requires a ticket on Delta.

What is Delta's car seat policy for infants?

Delta Airlines Infant Car Seat Policy

FAA-approved child restraint systems can be used in dedicated ticketed seats on Delta flights.

In case your child is seated on ticketed seats, you can use the certified child restraint system in accordance with eligible children, as per Delta policies. When your child is in an approved/recommended infant restraint/device, Delta will allow the use of a ticketed seat. The restraint must adhere to the applicable safety standards and have to be used as per manufacturer's instructions.

Parents must take care of:

  • Certification label on the restraint.
  • Installation – as specified by manufacturer.
  • Never put the restraint in an emergency exit row.
  • Do not install in seats where the aircraft seatbelt hinders approved seat mounting of the airbag in the seat.
  • The accompanying adult is seated beside the child.

Please check the aircraft configuration before choosing seats.

Are strollers and car seats free on Delta flights?

In the case of strollers or child safety seats which are checked in but not charged in accordance with the standard baggage fees, they will normally be processed at the time of drop off at the ticketing counter or at the gate.

Parents can help make mealtimes easier at the airport by:

  • The light weight Travel stroller.
  • Storing diapers and feeding items in the cabin.
  • Charging of strollers at convenient times to be checked in at the gate.
  • If you have a Delta Car Seat, be sure to have an appropriate travel bag for the seat.
  • Verifying the collection point with a gate agent.

Keep in mind, a free checkout on strollers or car seats doesn't imply free checkout on all baby equipment.

Does Delta offer bassinets for babies?

Delta Airlines SkyCot Baby Bassinet

Delta offers SkyCot baby bassinets on select long-haul international flights for eligible infants.

According to the current Delta information, bassinets are offered solely to babies under 25 pounds and max size is 26″ for qualifying planes. Limited availability and it is important to request one beforehand.

Parents should know:

  • SkyCots are applicable only on eligible aircraft/flights.
  • Availability is limited.
  • The baby must be removed at take-off, landing and as necessary by the seat-belt sign.
  • Availability is not a given just because the product meets the size/weight requirements.
  • Requests for bassinet should thus be considered requests rather than guarantees of a feature of a seat.

Does Delta provide baby food and family services?

Services provided to families may differ between flights and aircraft. Always take additional food and/or supplies as you cannot depend on the onboard supplies alone.

Helpful planning includes:

  • Pack sufficient formula or breast milk.
  • Carry extra diapers.
  • Bring feeding supplies.
  • Have extra clothes for the baby.
  • Before leaving, find out how many people are able to fit in the car with you.
