Traveling with young children requires careful planning and
adherence to airline regulations to ensure a safe and pleasant journey. A
common question among parents is, "Can my 3-year-old sit in my lap on an
airplane?" Understanding the rules and best practices for flying with kids
is essential for a smooth travel experience.
Airline Regulations for Child Seating
In the U.S., the FAA mandates that a 2-year-old and older must have an individual seat in a plane. That is, a 3-year-old cannot sit in your lap and will require a seat with a ticket purchased for them. As stated in the FAA, "children two and older will require a ticket and an individual seat in a plane."
International airlines have similar requirements. For instance, Turkish Airlines insists, "Passengers 2 years and older must occupy a seat of their own. They cannot sit in a lap of a parent, or an accompanying adult."
Safety Recommendations for Flying with Kids
Although regulations require older children over the age of 2 to have their own seat, safety experts recommend that all young children, even those under the age of 2, should be secured in an approved child restraint system (CRS) when travelling on an aeroplane. The FAA advises: "The safest place for a 2-year-old (and older) to be on an aircraft is in an approved car seat or in a child restraint system based on the child's weight.
The National Transportation Safety Board (NTSB) has also emphasized the correct use of restraints for young travelers. They have investigated incidents where unrestrained children have been injured and have advocated for stricter legislation to promote greater safety for children in an aircraft environment.
Choosing the Right Child Restraint System (CRS)
Selecting the correct CRS is important when traveling with a child. There are FAA guidelines to enable parents to choose an appropriately fitting restraint for a child according to its weight:
- Rear-Facing Seat: For babies weighing 0-20 pounds (0-9 kg).
- Forward-Facing Seat: For 20-40 pound children (9-18 kg).
Ensure that CRS is approved for use in aircraft. Look for a label stating, "This restraint is approved for use in automobiles and aircraft."
Booking and Seating Arrangements
When booking your trip, tell your airline that you will be travelling with a child and using a CRS. Some airlines offer discounted tickets for a child between the ages of 2 and 12. For example, Turkish Airlines mentions "You can enjoy a discounted child ticket if your child is between 2 and 12 years old".
To make sure you and your child are seated together, consider reserving seats in advance. Some airlines may charge you for seat selection, although recent proposals would ban the practice of charging families for this. The US Department of Transportation has proposed a rule that would force airlines to allow parents to book seats next to their infants without extra fees.

International Travel Considerations
For international flights, infant in lap policies (children under 2 years of age) vary. On domestic flights, several airlines allow lap babies to fly for free, but for international ones, a fee is sometimes collected, a portion of an adult seat price, and taxes and fee apply. Consult your airline for its policy and fee involved.
Additionally, other countries also have varying rules regarding child safety on flights. For example, the European Union Aviation Safety Agency (EASA) also recommends that infants and young children use a CRS rather than flying on an adult’s lap. If you are flying internationally, it’s best to check both airline and country rules before booking your flight.
Preparing for the Flight with a 3-Year-Old
Traveling with a 3-year-old requires careful preparation to ensure a smooth experience:
- Documentation: Ensure you have all necessary identification and travel documents for your child, especially for international travel. If you're wondering what proof do you need for a child to fly, some countries may require a birth certificate, passport, or a notarized letter of consent if one parent is traveling alone.
- Comfort Items: Bring along your child's favorite toys, blankets, or snacks to keep them comfortable and entertained during the flight. A familiar item from home can help soothe them if they feel anxious.
- Entertainment: Pack coloring books, stickers, or a tablet with pre-downloaded games or shows to keep your child engaged during the flight.
- Health Precautions: Consult with your pediatrician before the trip, especially if your child has any health concerns. If your child is prone to ear discomfort, discuss using pediatric earplugs, a pacifier, or swallowing techniques to ease ear pressure.
- Dressing in Layers: Airplane temperatures can vary, so dress your child in comfortable, layered clothing that can be adjusted easily.
- Snacks and Hydration: Bring plenty of small, easy-to-eat snacks and a spill-proof water bottle. Keep your child hydrated, as cabin air can be dry.
What to Do if Your 3-Year-Old Is Nervous About Flying
It's common for young children to feel anxious about flying. Here are some ways to ease their fears:
- Talk About the Trip: Explain what will happen at the airport and during the flight in a fun, positive way.
- Use Storybooks or Videos: Read books or show cartoons about flying to familiarize them with the experience.
- Visit an Airport in Advance: If possible, take a trip to an airport beforehand so your child can see planes taking off and landing.
- Practice Wearing a Seatbelt: Let your child practice buckling and unbuckling a seatbelt at home so they feel more in control.
- Encourage Deep Breathing: Teach simple breathing exercises if your child tends to get anxious.
In summary, a 3-year-old child must sit when travelling, with 2-year-olds and over required to have their own seat. For maximum safety, a child restraint system approved for your child's height and weight is best. By knowing the flight rules for children, choosing the ideal seating arrangement and planning ahead, your family can enjoy a safe and happy trip. With planning and a little patience, travelling with a young child can be a pleasant and hassle-free experience for both of you.
